Humor

I'm a founder of the campus creative writing club, and we generate new assignments weekly...last week I was tasked w/historical fiction. This week we are to craft something humorous.

Comedy has always evaded me. Next to poetry, I find it about the hardest thing in the world to write. Part of the problem is that humor is relative. Fart jokes work in middle school (and on sophomoric radio talk shows) and knock-knock jokes work on my kindergartener...

...and then I try to think of a timeless bit of humor, something that might still get a chuckle one hundred years from now. THAT's really challenging!

I am taking ideas, if anyone has any.
