The Antisocial Club meets every week at Jim's Bar. Since they are so antisocial, however, everyone always sits as far as possible from the other members, and no one ever sits right next to another member. Because of this, the 25-stool bar is almost always less than half full and unfortunately for Jim the members that don't sit at the bar don't order any drinks. Jim, however, is pretty smart and makes up a new rule: The first person to sit at the bar has to sit at one of two particular stools. If this happens, then the maximum number of members will sit at the bar. Which stools must be chosen? Assume the stools are numbered 1 to 25 and are arranged in a straight line.

Hint

Don't forget - the people sit as far away from each other as possible. If stool #1 is chosen first, the next person will always sit in stool #25.

mad-ade Jul 13, 2002	very good, but if they were really that anti social then they wouldn't go to a club in the first place.
NotSoLilGeorge Jul 13, 2002	Socaial Anxiety Disorder, heh? If people had S.A.D. they wouldn't go in the first place. Glad I could clear that up It's a favorite of mine anyways.
mad-ade Jul 17, 2002	Hey Curly, do you still see Larry and Mo these days?
NotSoLilGeorge Jul 17, 2002	Hey Curly, shouldn't you be dead. Oh wait, I just remembered, I'm not in heaven yet. You'll sure be gone then.
megan Dec 20, 2002	Its a good logic teaser. Its true that if they were antisocial they wouldnt go to the club in the first place, however thats not the point. It s a good one.
lilmommy Dec 18, 2004	I think this teaser wasn't hard but they weren't to clear in the question. So the way I read it made it sound like the next person that went to sit down sat farthest away from the last person that sat down. So i got 9 & 17 at first but some of my other answers were not the same. Like after 5, 13 isn't the farthest away, 21 is. That is how I interpreted it.
Nicky101 Dec 18, 2004	i don't think anyone's THAT antisocial! I would know...I'm antisocial ...Anyway, GREAT TEASER!
mary_13021 Dec 18, 2004	I'm not anti social..just buy me a beer! great teaser
stewartfreak20 Dec 18, 2004	What hateful people What kind of social club that if it's antisocial?! That doesn't make any sense. Good one
stewartfreak20 Dec 18, 2004	I think I meant to as,k what kind of social club is it if it's antisocial?! I think I'm retarded...
Therulerofthem Dec 18, 2004	if they are anitsocial, how would that plan spread
I_am_the_0mega Dec 18, 2004	"i don't think anyone's THAT antisocial!" Wanna bet?
smfsfnfmf4 Dec 18, 2004	im not anti social , so.... whatever
Led_Zeplin Dec 19, 2004	i didn't read it is to long and my head started to hurt. it's either that or i am lazy and dont want to read.
tommo Dec 21, 2004	I don’t understand why the first seat to be taken couldn’t be any odd numbered seat. For example the first person sits at 5, so the next one will sit furthest away at 25. The next will sit on 15 because that is the one furthest from both etc. until all odd numbered seats are filled. So the answer could be any two odd numbered seats.
Gizzer Jan 10, 2005	That won't work, tommo. If you have people in seats 5, 15 and 25 at first, the next people in will want to sit in seats 10 and 20. Then there will be only 11 seats taken at most: 1, 3, 5, 7 or 8, 10, 12 or 13, 15, 17 or 18, 20, and 22 or 23.
Gizzer Jan 10, 2005	Oops, forgot the person in seat 25! That makes 12 people, still not the maximum of 13.
Gizzer Jan 10, 2005	The original count of 11 was correct. No more counting for me until I have a nap.
tommo Jan 11, 2005	Of course! I didn't think that through. Thanks Gizzer.
marigold Feb 21, 2005	WHAT!!!!!!!!!????????? That made no sense to me at all!!!
chickwithbrains Aug 14, 2007	okay I kind of get it... but I looove the name of the club!!
bradon182001 Dec 19, 2007	Took me a while to understand the answer, but it does make sense I think. Once again I'm not real good with logic teasers. I guess my logic is not necessarily the same as others. Good teaser.
doehead Dec 19, 2007	EASY-EASY-EASY Also another repeat. I guess the editors are christmas shopping and don't have time to find new teasers!!!
tommysmo Dec 19, 2007	i liked this one.
UlsterCharlotte Dec 19, 2007	Meh.
UlsterCharlotte Dec 19, 2007	A lot better than the quizzes... I can't take any more Disney lyrics.
shawneeo Dec 19, 2007	That was a goodun, but, kinda harder than I wanted to deal with. I would 've had to actually use a real life paper and peyonsull, LOL, and THEN work out several different options before finding the right one, and... I DIDNT FEEL LIKE it! But that's how teasers are sposed to be, so, THANKS for the good teaser!!!
dogg6pound9 Dec 19, 2007	excellent teaser... obviously all odd # chairs need to be taken for max occupancy... that was the easy part... finding which 2 chairs forced that pattern... well, that took me awhile to figure out... love it... send another this way when you can
UptheHill Dec 19, 2007	I definetly need more coffee to understand this one!!
(user deleted) Dec 19, 2007	This doesn't make sense. "As far away as possible" doesn't mean that they can't sit next to each other if that's all that is available.
SweetPotato Dec 19, 2007	Fun, thanks, but too hard for me. However I think you can avoid all the questions about the anti-social premise ... just change the story to be about men choosing urinals in a rest room.
auntiesis Dec 19, 2007	Gave me some trouble, even though I knew it had to be an odd numbered stool I got hung up on which would be first.
GrandmaB Dec 19, 2007	As a math problem, something more in rules should be added to make sense of it. For example, why can't the 14th person sit anywhere between the other 13, the 15th sit anywhere between the other 14, and so on? The problem states that at any time, less than half of the 25 people are at the bar....isn't that 12 people? I assumed that was the given maximum, so I started figuring by assuming that was the maximum. Obviously, words were not conveying the picture well to this little mind.
jcann Dec 19, 2007	JD318 - the directions state that no one ever sits right next to another. I didn't have time to work on this one today, but I think it's a good teaser.
mondayschild59 Dec 19, 2007	That was a good teaser, cause it made my brain hurt. I gave up on it. Thanks for posting. I promise to do better next time. Monday~
LetsGoMetsJets Dec 19, 2007	Great one. Loved it. One of the best teaser's I've played!
jabdr Dec 19, 2007	I got the right # of people/seats but not by the right method. I didn't read the clue until after, and just had the bartender select #13 for the first to sit and worked outward in each direction ..I ended up not following the directions.
2ndhandrose Dec 19, 2007	It was so long I didn't try to solve it. Good stuff those who did Thanks anyway
lgleaves Dec 19, 2007	love it kind of
leroy_h Dec 19, 2007	this is goofy
wandering_goat Dec 19, 2007	Wow, excellent teaser. I just assumed that picking the first or last seat would work before checking the answer, but it sure doesn't!
Madelulabelle Dec 20, 2007	I love the title, that is what a lot of people think of homeschoolers as! I guess some of them are, but my group is more like hyper-social!!!!
vlerma Feb 05, 2008	I am sure it was a great teaser for logical thinking people, but since I have part timers it went right over my head. VVVAAARRROOOMMMM.
patiencewithaP Dec 19, 2010	Ouch...too early to make my brain work that hard I'll take your word that the answer is right!
Holografik May 01, 2012	This was a great teaser! It took me some time but I finally got it. What I don't like about it is that explaining how to get to the answer is way harder than actually getting there.
