Something amazing to tell you concerning physics and motion

[Buck]

3 friends go out to eat.

They get the bill and it is $25, but they don't really look at it too close.

They each give the waiter a $10 bill.

The Waiter decides since he cannot split $5 evenly among 3 people he decides to pocket $2, meaning the group paid a total of $27.

So the group paid $27 ($9 each), and he has $2 in his pocket, equaling $29.

What happened to the other dollar?
