From: Season 1, Episode 1
Jackass' first real bit, which came to be known as "Johnny Coxville" in re-runs, proves that everything is funnier with an erection. Knoxville sets out for a day of errands—including a game of pickup basketball, a trip to the guitar store, a pedicure, shoe shopping, and a workout at the gym—with a fake (and very promiment) erection in place.
We're not sure what's funnier: the people who mention it or those who don't. But a highlight of the bit is when he knocks over a guy's cup of coffee with his very visible penis.
