Get the killing joke mug.
The act of completely stripping a joke of all humor it originally possessed by trying to add something else after the telling to enhance the humor, but failing miserably. Characterized by silence and the two others present looking at each other in shock caused by the joke devastation. Also known by some in the Charelston SC area as "Jones-ing it"
Wyatt: What do a gynecologist and a pizza boy have in common?
Merrick: I don't know
Wyatt: They can both smell it but not eat it!
Jones: THAT'S WHAT SHE SAID!

Jones just joke-killed this by adding "that's what she said" when it is obvious she would not say this and it does not even remotely pertain to the current joke.
