I don't know much about it. All I know that it's from '80 and you can see it on "Magic Years" or "Freddie's Loves" I think, but you probably already know it :-) How about the sketch? Well, it has sth to do with a violence competition or sth like this. Kenny says that Freddie's the winner of the violence contest and tells him to do sth (I can't remember the exact words). Then Freddie jumps on Kenny.
