Like really morbid jokes.

Like one time I said "I play the Sims so I don't kill myself."

My husband said "You don't really mean that do you?"

I said "Eh. I'm not going to kill myself. It would probably be a bummer to find my bloated self hanging from the loft."

Or when my father and I would look through the obits "Did you find your obit? No? Phew!"
