There’s a song on Frank Zappa’s We’re Only In It For The Money called "Let’s Make the Water Turn Black" in which the following words are sung during the first verse:

And I still remember Mama with her apron and her pad feeding all the boys at Ed’s Cafe!

For the record’s initial release, MGM censored certain parts of the vocal tracks–including this line–without Zappa’s permission. Zappa tells the story in the semi-autobiographical The Real Frank Zappa Book:

"I couldn’t understand why anyone would chop that out. Years later I learned that an MGM executive was convinced that the word ‘pad‘ referred to a sanitary napkin. He became obsessed with the idea that a waitress somewhere was feeding sanitary napkins to people in a retaurant, and demanded (in violation of our contract) that it be removed. That guy needs to see a doctor."
