"Good evening ladies & gentlemen, this is you're captain speaking. You may have noticed your seatbelt signs are on, but don't worry, we've only come across a bit of a wager here in the cockpit. My co-pilot here has 50 bucks that says I can't get this baby into a barrel roll without the wings falling off. Well that's $50 he won't be seeing again, may the rest of your flight be pleasent & safe. Captain out."
