The joke that gets a laugh at a teammate’s expense costs you more than it earns.

A laugh at someone’s expense is borrowed from them and repaid by you later, usually in trust. Everyone in the room enjoys it and also notes that you will trade a person for a moment of attention, which makes them a little more careful around you afterwards. The target often laughs along, and that is not agreement.

Aim the joke at yourself or at the situation instead, which is nearly always funnier anyway. If one has already landed badly, apologise to the person directly rather than in front of the group. People notice that more than they noticed the joke.
