Comedy cliches and conventions

All comedy films have their own conventions to abide by and their own fomula, for example in adam sandler films they have a very familier formula which works, which is sandler will have to do a sport or adventure to get through and on the way meet a girl and win her and her heart and will live happily ever after, like in the films waterboy , happy gilmore and billy madison. other cliches in comedy are people always falling over and getting hurt which the audience finds as a guilty pleasure to laugh at someone being hurt, also someones hair in the comedy films mostly catches on fire which is hard to put out.There is also always a distraction from a girl and how the guy will go out of his way no matter what to save her or win her heart back normally its someone being hurt that brings them closer together.
