Taxiing Down the Tarmac...

Taxiing down the tarmac, the 757 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," explained the flight attendant, "and it took us a while to find a new pilot."
