With which of your parents do you share your sense of humor? My dad loves the absurd - Monty Python, etc. - basically anything unexpected. He also loves when comedic actors totally commit to their characters.
My mom usually likes the kind of "kids say the darnedest things" stuff and clever ironic stuff, but she can surprise me with something really out there:
We were discussing the Oxford Comma and she mentioned a grad student who dedicated his thesis to "My parents, Ayn Rand and God."
I said i thought that was unlikely, and my Mom (a regular churchgoer) said "what? You mean Ayn Rand wouldn't have sex with God?"
I was floored.
