Good thing I asked about the booze first!

My wife, ever the gracious hostess, was serving drinks at one of our parties over the Holidays. A friend of ours brought his brother who had just been ordained a Priest. She offered the friend a drink from the tray and said, "I'm so sorry Father, I'll go right back to the kitchen and bring you a coke."

The Priest smiled and said "No need. I may have alcohol. Priests abstain from sex, not the grape."

"Oh !" said my wife blushing, embarrassed "I knew it was something I wasn't supposed to offer you."
