One of my favorite scams in the beloved 27th FS....Squadron Commander "Bones," oft times somewhat unable during the normal day to speak eloquently, would find courage in the bar during Roll Calls. Quite often he'd yell "shot o' WEED!" at any minor infraction of the sacrosanct rules. The offender would have to take a shot to shut the man up. Made for slow going, especially during the "stories" stage of the event.
One Roll Call, the Mayor and boys decided to turn the tables. Four bottles of weed were procured--three empty and one full. The empties were filled with dark Lipton tea, and all were chilled to within a fraction of their life in anticipation of the Friday main event.
During that particular Roll Call Bones yelled his normal call of the wild, and others joined in frequently. All took shots, though Bones had no idea his was the only shot glass filled with the real stuff. Soon, he was happy and verbose. By 1900, he was absolutely rat-faced, only to realize that the wives were now patiently waiting to enter the bar for an official squadron gathering. Few wives were impressed. The boys were giddy with a successful scam.
As for Bones, the only fact he understood was that the Earth was trying to fling him off the face of the planet by mere centrifugal force alone.
He was a bit more subdued in the bar after that.
