New Olympic Sport - Stair bowling

Simple as can be.

 

1) Find old, cement, basement steps leading to your Mom's office

2) Set up cylindrical blocks on the bottom step in some sort of triangular arrangement

3) Climb to the top step

4) Hurl hard plastic bowling ball down the steps in attempt to knock down all the "pins" and get a strike

5) Laugh hysterically as your Mom pisses herself as a result of the surprising clamour

 

YOU'VE WON!
