A Man and the Club
Trick brain teasers appear difficult at first, but they have a trick that makes them really easy.
Tim really wants to join the new luxury fitness club that opened up downtown. The only problem is that to join you have to sign up at the desk and, to get inside, you have to answer a riddle. He thinks this won't be too hard. The guy in line before him goes up to the security guard. The guard says "six", and he answers back "three". The guard lets him in. The next lady goes up and the guard says "twelve". She says "six" and goes in. Now it is Tim's turn. The guard says "four" and Tim, thinking he was so smart, says "two". The guard says "you're wrong". What should he have said?
Answer
He should have said FOUR.
SIX has THREE letters. TWELVE has SIX letters. FOUR has FOUR letters.

| This is an example of a well known mathematical black hole. Take ANY number you want and count the characters. Write this out and count the characters of the result. And so on... You`ll converge to FOUR and get stuck there. An example: 2416 Two thousand fourhundred sixteen --> 19 Nineteen --> 8 Eight --> 5 Five --> 4 Four --> 4 |

| One thing this teaser demonstrates is that Braingle ought to provide a spelling checker to those who submit teasers, and/or the editors ought to use one. |

| When I looked at the answer and saw certain words capitalized, I felt stupid like you were putting emphasis on the answer. lol That's just me though. Not bad. |

| I'm fairly certain that this teaser was submitted first, making the other one a duplicate, and this the original.
I loved it! Keep up the good work!  |
