I just can't help it. Every time I'm sitting in church and Communion comes around, I can't get Tom Lehrer's "Vatican Rag" out of my head. "...get in line in that processional/ step into that small confessional/ there the guy who's got religion 'll/ tell you if your sin's original/ if it is try playin' it safer/ drink the wine and chew the wafer/ 2, 4, 6, 8/ time to transubstantiate..."
Once it's in my head, it's all over. I end up bopping around to that tune for the entire rest of Sunday.
