Bumbling Bad Boys

Typically a pair of assassins, comic relief villains are a common element in the series. They are usually mercenaries employed by the mastermind of the film. They range from from being deadly (to side characters) to being cartoons, but most think they have a profound outlook on life that comes off as idiotic.
