A large, two-engined train was making it's way across America. While crossing the Western mountains, one of the engines broke down.
“No problem, we can make it to Denver and get a replacement engine there.” the engineer thought, and carried on at half power.
Farther on down the line, (if you didn't guess) the other engine broke down, and the train came to a standstill in the middle of nowhere.
The engineer needed to inform the passengers about why the train had stopped, and always trying to look on the bright side of things, made the following announcement: “Ladies and Gentlemen, I have some good news and some bad news. The bad news is that both engines have failed, and we will be stuck here for some time until the additional engines arrive. The good news is that you didn't take this trip in a plane!”
