Which film/television programme is this from?

I only remember two parts from it, one is that there was a guy who wanted to play american football for some team, but then he broke his legs or something and wouldn't be able to. Then to try and fool the coach who was coming over to his house to see if he was fit enough, suspended himself out of the window and got a guy to zip his head inside of a jacket so that it would look like he had no head, after this he made it look so that his head was attached to the other guy's body, and this plan failed so the coach drove away and the guy with the broken legs chased his brother (who was riding a bike) angrily and ran past the coach in his car whilst he was doing 40 miles an hour
