DM: You encounter a very angry polar bear.
Me: Polar bears aren’t supposed to be this far south, are they?
DM: No. No they are not.
Bard (half jokingly): I use my speak-to-animals ability to try to convince it to join our party.
DM (dead-serious face): Roll diplomacy.
Bard: Oh. Uh. Okay. *rolls nat 20*
DM: … The polar bear joins your party. That wasn’t supposed to be that easy.
