LOL!!! This so reminds me of what I did to the shop numnut not too long ago! We were rigging ailerons on a Lear 60 and I needed the inclinometer. I sent him to the stockroom to get the, not the digital one, but the special "Flugelbinder Inclinometer" and he looked at me funny. All I could do not to laugh, but I held it in. I acted real serious and he went to the stockroom. I proceeded to tell everyone on the aircraft and they were watching for him to return. He finally came back after ten minutes of searching in the stockroom. He even had the stockroom people (4 of em) looking with him. When he told me the stockroom wanted to see me, everyone lost it!! It was all we could do not to piss our pants. Needless to say I was in the office about an hour later getting chewed for wasting so much company time (50 people x 10 min ea =500 min). The boss that chewed me though was laughing the hardest.

Jet wash is another good one!!
