Post your favorite brainteasers. Throw your answer in a spoiler. If you want to comment on the answer of a brainteaser, post the first sentence of that brainteaser, then throw your answer in a spoiler. Begin:

You have nine pingpong balls. All of them are the same size, shape, color, etc., and there's no way to discern between them by touch, sight, etc.; however, one of the nine balls weighs slightly more than the other eight. The difference is so slight though, that you can't tell which ball is the heavier ball by picking the balls up or anything similar. The only thing you have that can accurately measure the difference in the one ball's weight from the other balls, is an old school balance scale (think the judge's balance, or what you used in high school science; when you put something on one side, that side will move downward and the other side will move upward. The catch here is that you're only allowed to use this scale twice to find the one ball that weighs more than the others. How do you do it?

Solution:
In order to solve this, you first have to split the balls evenly into three groups. You add one group to each side of the scale, and you leave the third group alone. If the scale is balanced after putting the two groups of three balls on the scale, then that means the heavier ball is in the group that's not being weighed. If one side of the scale is lower than the other, then obviously the heavier ball is in that group. Once you've figured out which group the heavier ball is in, you put two balls from that group on the scale, leaving the third ball off. The same thing applies here: if the scale is balanced, then the ball that's not on the scale is the heavier ball. If one side of the scale is lower than the other side, then you know that ball is heavier.

Post your favorites NT - works gets mad boring and it's always fun to get the mind moving again.

A wolf, a sheep, and a cabbage need to cross the river. How can you bring them across, one by one, without the sheep eating the cabbage, nor the wolf eating the sheep?

Take the sheep across
Come back
Take the wolf across
Take the sheep back with you
Drop the sheep off, take the cabbage
Drop the cabbage off with the wolf
Go back
Get the sheep
Bring him with the fam
Smoke a blunt
 
a horse travels a certain distance each day. two of its legs travel 30 miles each day and the other two legs travel nearly 31 miles. it would seem two of the horses legs must be one mile ahead of the other two legs, but of course this can't be true. since the horse is normal, how is this situation possible?

3rd leg is his penis
He'd been have sex for almost a full mile's length of time

:lol:

That's wrong. Your answer is about a 3rd leg-penis while the horse in the riddle has two legs that travels 1 mile more than the other two legs. You haven't accounted for the other leg and it's a normal horse so no it doesn't have 2 penises.

Horse is on a circle or oval track and is inside legs travel less distance than the outside legs.
 
The horse riddle has nothing to do with the horse's actual legs; it's referring to the "legs" or part of the trip it takes in a day, 61 miles all together. 2 "legs" of the trip equal 30 miles, the other 2 "legs" equal 31.

That's my guess at least!
 
Three men go to a pizza parlor. They order a pizza that costs $30. They pay the waiter $10 each for the pizza (10x3=30). The waiter takes the $30 to the cash register where he realizes the pizza actually only costs $25. The waiter goes to give back the men their $5 in change. On the way, the waiter realizes that he cannot split the $5 three ways so he decides to pocket $2 for himself and gives each man back $1. This means that each man paid $9 per person for the pizza. The waiter pocketed $2. so 9x3=27. 27+2=29. What happened to the last dollar?
 
From the breakfast club thread..lol..

Ray J initially mentioned 7 Rolls Royces when he first started..
then 7 Went to 5 Rolls Royces then it went to  3 NEW Rolls Royces. How many Rolls Royces are new and how many Rolls Royces left and how many Rolls Royces stayed by the end of the call?

The waiter is a dumbass and sucks at math, probably why he is a waiter. Should have pocketed the $5 in full as a tip.

It seems like the waiter counted $1 twice. If each person pays $9 for the pizza, he should keep $3 and only give back a dollar to two people...

I guess???

30-2+28 though.
