What's your darkest joke?

There was a parrot that cursed a lot
His owner got mad and threatened to put him in the freezer to punish him
but the parrot wouldn't stop so his owner put him in the freezer for half an hour
when the owner let him out of the freezer the parrot came out and asked, "what did the chicken do?"

I was going through cancer treatment over 10 years ago, and I was at the supermarket, newly bald from chemo. The cashier, who I was friendly with, said "Man, you could really use a drink rn!" I looked at him, totally deadpan and said "A drink?! That stuff'll give me cancer!" He looked at me, shocked, and then I smiled at him, and we both started laughing.
