A large two engined train was
crossing America. After they had gone some distance one of the
engines broke down. "No problem," the engineer thought,
and carried on at half power. Farther on down the line, the other
engine broke down, and the train came to a standstill. The
engineer decided he should inform the passengers about why the
train had stopped, and 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. The good news is that you decided to
take the train and not fly."
