Wedding speech prank

I'd like to ask the bride and groom to participate in the speech now. Linda, if I can ask you to place your hand flat on the table, and Paul, if you would place your hand directly on top of Linda's. Are you enjoying that buddy? Make the most of it, because it's the last time you'll have the upper hand.

It's a real honor to be Paul's best man today and, in the spirit of giving and receiving gifts, I would like to take this opportunity to present Paul and Linda with a rather belated housewarming present to welcome everyone into their marital home.
