I have two potential jokes for a hypothetical Conan Ressurection Scenario.
First, you can have them ask how a wizard ressurects a cleric and you can try to explain through RPing that his character class is a cleric but his people refer to him as wizard (the word wizard is based off of wise and clerics use wisdom after all). For an example of a similar joke consult Order of the Stick #209

He seriously regretted his choice of taking a level of cleric and is almost happy to lose a level being ressurected because now he can go back to be a fighter. (I don't know if you lose levels being raised in first ed though)
I wish I had something for the horde of incorporeal demons because I am a big fan of Conan, but that scene strikes me as ueber-corny and it often makes me laugh, as opposed to when I laugh at great dialogue. My favorite in the movie series is:
"I suppose nothing hurts you"
"Only pain"
Joke 2.5, the horde of incorporeal demon-like things comes because the wizard (whose actually) a cleric tried to cast a spell way above his casting level and has angered his god.
