Rectum? Dang near killed him!
For some reason, I first read that as "Dung near killed him". :-)
That particular punchline has rattled around in head for many, many years. Alas, I'm at a loss for the set up.
I'm glad there's another person on the planet who remembers it. If you know the whole thing, could you pm me? It might give me some peace.
