Jester
From GemMarkle DND

Jester is the Chaotic Neutral goddess of humour. They are often depicted as inanimate objects that do nothing in particular, are simply in an absurd location for that object. Their symbol is a yellow circle with two eyes and a smile. Followers of Jester are required to sacrifice any amount of good will allotted them if doing so will make someone laugh.
Prayers to Jester are traditionally ended with the phrase, "Yeah, but it was worth it."
