Comedy Relief In Role Playing Games

The idea of using role-playing games for comic relief applies not just to games that are already intended for comic relief, either the system itself (such as Paranoia, HOL, etc), but to more standard (usually "serious") game systems where the players all agree to give comedy a run. Playing for comic relief can even be done on a per-character basis, even within a game that is NOT geared toward comedy, though the style, content and intensity of this type of play is best kept within the players' overall tolerance for "shenanigans" - this is not something one should do.
