Dahmer's Ketchup

Listen here, you little goofball, you posted this joke. You are clearly not bright enough to understand it. Jeffery Dahmer was a real person and a really bad man. He was a serial killer and cannibal, who ate his victims. The punchline, "This isn't ketchup," suggests that someone mistakenly thought the human body parts were ketchup. Get it? It's dark. It's morbid. It's not funny for normal people, but you are not normal.
