You can make your point without making them the punchline.

A joke at somebody’s expense wins a room instantly, which is why it is tempting when you already have the better argument. The trouble is that the laugh becomes what people remember, and your point leaves with it. You also hand the other person a reason to defend themselves instead of think. Funny and persuasive can pull in opposite directions.

Make the point plainly first and see whether it holds without the joke. If it does not, the joke was carrying it. Save that line for someone who can take it and knows you mean nothing by it.
