Once, at a previous job, a co-worker wanted to send an indirect message to another co-worker who frequently ordered fast food items that were difficult to carry, would spill, or weren't on the menu. He announced his order in the office, ostensibly writing down, "One order of chili and three bowls of soup." Another co-worker, catching on, said he wanted three shakes with no lids. We continued around the room this way. When it was my turn to order, I said I wanted a vat of molten lava.
Unfortunately, the offending co-worker didn't catch on--or acknowledge it, if he did.
