Random Song Lyrics of Silliness

A corpse is a corpse, of course, of course,
And no one can talk to a corpse, of course.
That is, of course, unless the corpse is the famous Mr. Dead.
Go right to the source and ask the corpse.
He'll give you an answer full of remorse.
He's always an unsteady corpse.
Talk to Mr. Dead.

Yes, this is a re-lyricing of the Mr. Ed song.
Yes, I know that there's a fuller version, but no smoothly-integrated ideas popped into my head for the part that almost nobody remembers.  If I think of something, then I'll amend this post.
