As the plane reached cruising speed with the seat belt sign switched off, a 6 ft 3" black man with the build of Mike Tyson in the front row got up from his seat, turned to face the back, raised his arm and yelled, "HIJACK!"
Everyone was frozen to the seat, expecting the worst to happen.
The two Air Marshals were about to jump on the guy and overpower him when another voice answered from the back of the plane:
"HI JOHN!"
The moral of the story is:
If you have a friend named Jack, for heaven's sake don't ever greet him on the plane.

Monyet King ha ha .... Have a pleasant day, MWS.
