I'm flying Air Canada from Halifax to Toronto on a 747 that's come in from Paris. An hour into the flight, the Captain announces that he had to shut down one of the four engines because of a problem. He says not to worry, this 747 can fly very well on 3 engines but we'll be about a half hour late arriving in Toronto.

A little while later the Captain announces that he had to shut down the second engine but not to worry because a 747 can fly just fine on 2 engines. But we'll be late arriving in Toronto by another hour.

Amazingly, about 15 minutes later, the Captain announces that he's lost engine #3 but not to worry because a 747 was designed to fly quite well on just one engine. But we'll be delayed by another 2 hours arriving in Toronto.

The guy sitting next to me, who's been suspiciously silent throughout all these announcements suddenly blurts out in the loudest voice so everyone on the plane can hear, "Ya know, if we lose that fourth engine, we're gonna be up here all fu**ing day!"
