The tragic thing about comedy writers is that they very rarely get to make proper jokes themselves, so when you do, it is a big day for everyone.
INT. BAR - EVENING
PATCH: So we'll be meeting my cousin for a meal, and her boyfriend Hugo's coming, who's Norwegian.
ME: What does he do?
PATCH: He studies reindeer movements.
ME: (QUICK AS AN ACTUAL FLASH) Won't take long, they're basically just (makes galloping motion) with the occasional (tosses antlered head).
PATCH: Yes, very good.
ME: Hahhahahaha! I am comedy.
Five minutes later I get Patch to tell me about Hugo again, so I can make the same joke.
If anyone else out there knows someone who is studying reindeer movements, they can use the joke too. It is an Open Source Reindeer Joke.
