Comedy Track - Unknown Comedian "Oswald killed Kennedy, I shot Oswald"

The joke went a little like this:

"I remember when I was a kid Oswald got shot, and my mother came out and screamed Oswald got shot Oswald got shot, kids, get in the house! As if Ruby said: Oswald shot Kennedy, I shot Oswald but I won't give up until the Kimmel kids are dead."

Now I thought he said Kimmel so I started searching for that but I doubt it's Jimmy Kimmel since he doesn't do much stand up. Please let me know if you know this joke.

Found it. Jimmy Tingle on the CD Strange Bedfellows.

Well done - it had me baffled.
