C-cup 

The reason why girls don't need to lose weight.
D-cup is even better!

Girl: Does this shirt make me look fat?
Guy: A bit, but it makes your boobs look sexy! And don't go on any diets, keep your C-cups!

Ball in a cup 

The most fun that you can possibly have... on a budget.
It's basically a large wooden cup with a handle to grab, attached to the handle is a string, and attached to the string... is a ball. The goal is to get the ball, in the cup.

I went in to town and saw some broke looking kids, they played ball in a cup for 2 hours!
