Airport Security alerted an airline

Airport Security alerted an airline crew to keep an eye a blonde passenger who appeared excessively nervous and shifty-eyed.

Soon after takeoff, the blonde man called a stewardess to his seat and said, “I have a live grenade in my pocket. I’ll blow up the plane if you do not divert to Cairo.”

Perplexed, the stewardess said, “But, sir. This is TWA flight 1219 to Cairo.”

“Damn!” replied the blonde passenger, “I got on the wrong plane.”
