You should get ahold of the old Paranoia module from the 1980s called Orcbusters. It's a whole book of these cliches. The story is that the troubleshooters are inadvertently transported to an alternate reality via a "transdimensional collapsatron." There, they find themselves in a D&D dungeon.
The only part I remember was their fabulous Wandering Monster Waiting room. The room contained a table, around which were seated monsters of various species, one of each. I recall a bugbear, a kobold and a gelatinous cube I think from the original. They were playing poker. And once every 15 minutes, whoever got the low hand had to leave the room and wander around the nearby corridors, trying not to get killed by adventurers.
