How do you keep a blonde in suspense? Anyway, there is a whole bunch of ways to find good jokes for just about any occasion. It is really just a question of who your audience is going to be.
Canon printer geeks go to conventions, politicians go to their lobbyist. Get it? Politicians/ lobbyists… well there’s no accounting for taste.
So, head for the people that you want to make fun of. Most people have a pretty good sense of humor and are ready to laugh at themselves.
