What do you do after you've sung a verse of "Lamb of Biff*" to lessen a grating co-worker's impact? If you were in my shoes over 20 years ago, you agreed to a co-worker's suggestion, "Now, let's sing it as a round. Drew, would you start?"
I started singing, "Lamb of Biff*, you take away the sins of the world..." Three other co-workers joined in with that same verse at the appropriate times.
When you can't change another person, you can at least sing a verse of "Lamb Of Biff*."
*--not the offending co-worker's real name
