D&D jokes?

A dwarf, a human, and an elf walk into a bar and order drinks. Before the first sip of elfwine a bar-fly lands on the rim of the elf's drink.

"It's ruined, I can't drink it now," complained the elf.

The fly flew over and landed on the human's glass of meade. The human waved it away, saying, "It's just a fly."

The fly landed on the dwarf's beer stien, and the dwarf grabbed it by the tail and squeezed, shouting, "That's mine! Spit it out!"
