Guy Gets Excited After Successfully Doing Trick Shot With Cup and Slips Down Stairs

This guy was sitting on top of a flight of stairs trying to make a bank shot with plastic cups. He would throw the cup one by one, bouncing it off the wall, hoping it would fall into another cup kept at the bottom. He had been trying for three hours and was getting frustrated with his futile efforts when suddenly one cup fell inside. He screams in joy, and his excitement causes him to slip down the stairs.
