It takes the form of a story, usually with dialogue, and ends in a punch line. It is in the punch line that the audience becomes aware that the story contains a second, conflicting meaning. This can be done using a pun or other word play such as irony, a logical incompatibility, nonsense, or other means
Mike Newell's influence; ”"I come from a school where making it funny is what matters. Mike was obsessed with keeping it real. Every character, no matter how small, has a story, not just three funny lines. It's a romantic film about love and friendship that swims in a sea of jokes."
Curtis chose to omit any mention of the characters' careers, because he didn't think a group of friends would realistically discuss their jobs while together at a wedding.
