"Hey, I heard you were a bit down—where's John?"
"He died."
"Oh, I'm so sorry, but I got you food."
(After they eat) "Hey, how did John taste seasoned and cooked?"
Alright listen up, you chucklehead. This joke is dark. Someone asks about their friend John, finds out he's dead, then eats some food, only to find out they ATE JOHN! It's funny because it's messed up, like your search history, I bet.
