What's the funniest thing you've caught someone doing?

Taking a dump behind the house. XD

Some guy at my school getting kicked in the balls by the gf he just broke up with.

I caught my neighbor in his back yard he was literally choking a chicken, I laughed at him and he does not even know why

Two boys shoplifting - it wasn't the shop lifting that was funny, it was when I caught them.

Their reactions were priceless.

when my friend was trying to jump over some one from 1 ramp to the other using his skate board, i tried laying down for him to do it he made it then another friend tried it and then he landed on him, that was funny

A guy sunbathing wearing a thong.

Caught my old boss scrating between his butt, then he tried to shake my hand.

my friend's bf was so drunk one night, he was peeing on the hood of his car at someones party. then i seen someone at the mall walk into a pole.

when a friend of mine whispered to himself, "I thought i got smaller..." in the hospital after being bashed hard by a car!!!

scratching their butt and then after smelling their hand

I yell to them "stop doing that in public, *****"
