Cream pie is a kind of pie that is filled with custard or pudding. The custard that is filled can be made using ingredients including flour, milk, eggs and cream. Cream pie comes in various flavors like lemon, vanilla, banana, chocolate, lime and coconut. Almost all the cream pies are topped with whipped cream. The pudding filling relates to French crème patissière, a chief component of French tarts and cakes. Comedians often use a cream pie as a gimmick. When a cream pie is used for any show business, a mock-up pie is used that is made with shaving cream and it looks real. Cream pie is also used as a weapon for protest by political activists. It is thrown on the face of unsuspecting opponents.
