This reminds me of a song to which I only know a few lines, about Mr. Snoop & Mr. Peep:

If you wake up to discover you've been murdered in you sleep

Send for Mr. Snoop and Mr. Peep.

I always though this was the theme song from an old radio show, but maybe it is actually part of the same song as Mr. Not and Mr. Shot???

(Does anybody know anything more about Mr. Snoop & Mr. Peep?)
