Eatable Vestments

So, Reverend Lovejoy and his wife on the Simpsons rekindled their sex life after getting Homer and Marge’s mattress. (To understand how they got the mattress in the first place, you will have had to have watched the episode.)
The Lovejoy’s station wagon pulls up in front of the house. They jump out and run towards the front door. The Rev. Lovejoy says, “You put on the Michael Bolton CD while I put on my eatable vestments.”
Eatable vestments. That’s funny.
