Taxiing down the tarmac, the jetliner abruptly stopped, turned around and returned to the gate. After an hour long wait, it finally took off.

A concerned passenger asked the flight attendant, "What was the problem?"

"The pilot was bothered by a noise he heard in the engine," she explained.

"Oh, and it took a while to fix it," said the passenger.

"Not exactly." replied the stewardess, "It just took us a bit to get a new pilot here."
