That was a good teaser.. Neither me or my friend could figure it out.. great job.

Good one! But I didn't get it. Then was the hint to throw you off course?
That was a good one, I got it with out reading the hint- but once I checked the hint I was thrown off! Good one.
I really liked this one! Keep up the good work!
I cant believe it!!!
U TRICKED ME...
I thought it was 45 shakes
U TRICKED ME...
I thought it was 45 shakes
Good one! I didn't get it the first time.
Nasty! Your hint is NOT a hint - it's a misdirection of the first order! I had foolishly assumed that a hint was supposed to aid one in arriving at the correct answer! Silly me
I LIKE IT.....
Very, very clever!
You definitely got me
I started working it out, but then thought, hang on a minute, is this right? I looked at the category (Trick) and then I got it immediately! Good one! Just one flaw - why on earth would you only want to shake hands with people smaller than yourself?
i thought it was really easy, but i didn't think about the people being taller, only shorter! very funny, though! i should've looked at the categorie. it sure tricked me!

wow! that was a good teaser, gets you thinking!! the hint wasn't really a hint! it confused me more but anyway good teaser

Thanks alot fot the hint!
I would think that that was a duplicate. I've seen another one exactly like that. But, I like them both! Great teaser!

lol.......very easy....Why does it have such a high difficulty rating?
That was very easy and I knew the answer as soon as I read it. I looked at the hint just to see what it said and thought it might have been to deliberately throw one off! I stuck with my original answer and was correct. Good job.
OOOO MMMM GGGG !!!!!!!!
R U guys serious, or just being nice???
Not only was it a dup of the tennis one, but I think it was way too easy and kinda dumb. I'm not trying to be mean, but I figured by the difficulty rating I would have had to think more than 2 seconds!

The tennis one is entitled 'better than the best' and it got a 1.31 dificulty rating. I still think that is too high.
hey, kcelf, be nice. i got it easily but i still liked it.
kcelf, be cool It was easy but that shouldn't stop u from liking it. Didn't stop me. And short people rule the world. I should know, I am one.
yeah it is the same as the tennis one, and both of them take about ten seconds to figure out
Of the hunderds of teasers I've seen, this is the first I just added to my favorites list. Awesome teaser!
I didn't get it! then again, i never get any of the teasers!
i love this one. its one of my favorites! my math teacher and i were really stumped!
That was pretty cool. The hint was kinda funky and i actually got that answer (45) but i knew it was a trick question so i was stumped. I only want to know why you put the 45 thing as a hint!
it was evil of you to do that as a hint
but still a good teaser and why would anyone want to only shake shorter peoples hands?
but still a good teaser and why would anyone want to only shake shorter peoples hands?
Good one. THe hint almost threw me off. If i had not read a simliar teaser befor i may not have gotten it.
good one but if u think a second it will give answer very funny
Good one, and a nice hint to match. Keep them coming.
WOW , either some of you don't understand the concept of trick teasers, or you just can't stand being tricked.
This was a classic, especially with the trick hint.

Thats the problem. It's a classic. It's unoriginal. Ah well, nice try anyway...
That was a good one. Not hard, but good.
Good job! Assuming that after they shook hands with someone, the ladies put on heels...
this is based off of a joke you pull with a large crowd all sitting, like a church. You say: "Everyone shake hands with the person directly behind you." Everyone will turn around to shake hands, and everyone laughs.
YOU PUT A FAKE HINT?!?!?! I guess it is a trick. Good thing I saw it b4
great riddle
Shouldn't the editors have caught this as a duplicate to the "Better than the Best" teaser?
O_O I HATE THIS TEASER!!! noooo.... I LOVED IT u totally fooled me > x)
Yeah, that was pretty easy. But really, I think the hint is meant to HELP people not intentionally misdirect them. If you don't want to make it easier, just don't give a hint. You're not giving the ppl who don't get it in the first 2 seconds a chance!! Common but good teaser.
Lame, way too easy. And, no, that so called hint wasn't there to help people.
Classic - and a very good one, too!
Thanks!
Jim
Thanks!

started to do the math, then realised the trick. Good one!
Very cool. I did the math in about 2 seconds, and was so proud of myself when I read the hint. Busted !!! I was so fooled it isn't funny. Never noticed the category was trick. I feel so dumb, but I still love it.
Glad I skipped the "Hint" on this old chestnut.
Misleading info should be discouraged, even if meant in fun.

Very clever, and the Hint was certainly not a hint!
I'm an idiot. I got 81 as the answer working it out. I forgot it was a trick and a really great one....love this tricky teaser.
Thanks for a good laugh
Almost got me for a second. I started out thinking "There are 9 people shorter than the tallest person, 8 shorter than the next ....but no one would want to shake the tall guy's hand ....hang on what category is this in?" Then the lightbulb went on and the answer became clear.
Fun!
Fun!
Very old and very easy teaser. I've heard this in many different versions
These kind of teasers are my favorite, really tricky and wakes me up
That was a good one... easy but creative in a way... good job... its definitely going on my favs
jcr thanks for the help on yesterday's teaser.
That trick was good!
Sorry, this is a junior level trick!
Nice. A probability parody. I saw it right away, but i could see people start doing some calculations. That fact that it is not hard does not mean it is not good. I'll share this with people interactively. Quite humorous.
