Donald Duck was appearing at Las Vegas for the Christmas season. One night after the show, he spends some time in the bar and meets a really hot lady duck. They get on well together, so he invites her to his show the following night.
Then he suggests they go back to his hotel suite. On his way past the hotel reception, he asks the clerk discreetly if he could get him a contraceptive - just in case, you understand.
Donald and the lady duck go up to his suite and just as they are starting to get really smoochy, there's a knock at the door. "Come in", shouts Donald, whereupon the room service guy comes in. "Mr Duck, sir," I have your contraceptive. Shall I put in on your bill?"
"What," storms Donald, "do you think I'm some kind of pervert?!"
Sorry - off topic, but it is Christmas!
Reckless with caution.
