Welcome to yet another (psychotic) episode of Walk The Prank.
Kids, don't try this at home. Adults, don't try this at the airport!
In a kinder, gentler era there were still airport security and X-ray machines.
Setup: The band I was with booked the Xmas holiday shows, (including New Years), for as much money as we'd made all year. The drummer then decided he had to go home for all those hollow days.
After many hours of 'discussions,' there was no changing his mind.
Prank: We decided to give him a parting gift. We drove him to the airport, saw him to his gate and gave him his christmas gift. It was from all of us. The box contained his favorite drumsticks, gilded and inscribed with his name.
Unbeknownst to him we'd also cut the shape of a .45 caliber pistol out of tinfoil. We inserted said tinfoil between the wrapping paper and box of our gift. We saw him off at the gate and handed him his gift.
He was touched.
Fun part: Observing from the balcony as he was detained and searched over and over while he missed his flight.
Extra fun part: He was touched ... in the way only a jailhouse matron can do.
(Maybe you had to be there;-)
