Once, trying to solve a puzzle, a player called on the names of divine beings for help.
"ODIN!....THOR!.......HASTUR!"
WAAAAAAY back in the early 80's, they did that same thing as a joke in the Fineous Fingers comic strip in Dragon Magazine, though, as I recall, they were trying to get past a locked door that had frustrated Fineous (the self-proclaimed "Greatest Thief in the World").
