Suspense in the air

I recently heard that on a flight out of the UK, the pilot made an announcement.
"Ladies and gentlemen, this is the captain speaking. We are currently at, Oh my God".., a pause of several seconds, then he continued, "Sorry, one of the flight attendants accidentally spilled a very hot cup on coffee on my lap; you should see the front of my pants".
A passenger at the rear of the plane shouted, "You should see the BACK of mine".
