The B-word -- avoid it at all times in an airport, even if your stomach is the only thing that's on fire.
According to Msn.com, Jason Michael Cruz learned the hard way not to mention the word "bomb" in an airport. Cruz and a friend were detained at John F. Kennedy Airport in New York after a TSA employee overheard Cruz tell a friend about having a "bomb."
Turned out the bomb was a sandwich that was making Cruz feel queasy.
Cruz and his friend missed their flight.
