Some things I wonder about:

If a door is ajar, what is the flavor of the jamb?

If they get olive oil from squeezing olives; peanut oil from squeezing peanuts and orn oil from sqeezing corn; where do they get baby oil?

Why aren't there any Himmacanes?

If you were to choke Papa Smurf, what color would he turn?

If you have any more (and not the old standards from George Carlin) please let me know.
