Remember when Bill and Ted run into copies of each other in the time loop? One set says "Hey, dudes, how do we know it's really us? What number are we thinking of?" and the other set says "69 Dudes!" Well, we watched it the other night and the kids loved it.
At their age, they only get part of the joke. So, night after night at the dinner table, with much hilarity, we hear, over and over, "69, Dudes!"
Ha ha ha ha ha ha ha.
