Back in the late 80's, we were playing through D2 Shrine of the Kuo Toa. I was DM. The players reach a pool shrine of Blibdoolpoolp, which they know full well is a holy of holies, sacred, inviolate, etc. Then the magic user says: "I stick my staff in the water and stir it up." That brought on a whole heap of trouble, and the wizard called his staff a Staff of Stirring ever since.
In our current campaign, the party found a Deck of Many Things. After suitable research into its functioning, everyone declined to draw. Except... our jaws hit the floor when the barbarian said, "I draw four." Wow. And they were all bad, too, but at least he didn't get void or donjon.
