Funniest moment in the movie
Cornholio's appearance in the cockpit, and the pilots' startled reaction.
A friend of mine saw this film before I did, and he told me, "I'm not going to spoil anything by telling you which scene it was, but there was a moment in this movie when I was laughing so hysterically that I almost had to get up and leave the theater."
That's exactly the reaction I had when Cornholio burst in on the flight crew, causing them to almost wreck the plane. I asked my friend, and sure enough, that was the moment for him, too.
Priceless.
