There is a reason why a lot of classical jokes start out with 3 individuals walking into a bar. It isn’t because the punchline to these jokes are any better than “Why did the Chicken Cross The Road?” or “Knock-Knock… Who’s There…”
It is because by starting the joke out with 3 variations of people it drastically raises the chances that 1 of the cohorts in the joke resembles or has characteristics of someone in the audience.
