Tell 'em about the pilot who called Air Traffic Control wanting to know
what time it was. The controller asked, "what airline was that request
from?" Sez the pilot, "why do you want to know that?" "Well, sir, if
you're American, it's 2:30. If you're United, it's 1430 hours. If
you're TWA, it's 1930 Zulu. And if you're Continental, it's Thursday."
