Oh, well:

Zorro was a swordsman brave,
Until he ordered bath and shave
And was discovered by the maid
To be the gayest Spanish blade.
Burma Shave.

Mrs. O'Leary's cow was really male
While shaving kicked the fatal pail --
He complained: This razor's not adjustable!
And then: My, my, I'm combust-a-bull!"
