Hands down, the funniest game I ever played was John Terra running Paranoia at OGC in New Hampshire. Which session of Paranoia, I cannot say, because I made it a point to play in his adventures year after year and they have run together in a glorious mish-mash of secret agendas, poorly understood prototype weaponry and keeping one worried eye on the number of clones remaining.
I was highly suspicious of Paranoia when I first played in one of John’s games. It seemed like a recipe for a miserable time of backstabbing and “ha ha, I win.” I forget how I got past that initial perception, but I did. The backstabbing still happened, but the community spirit at the table was persuasive, and John’s an amazing GM who does an amazing job of making player choices matter while including everyone who puts themselves forward to participate. And the adventures are littered with themed puns. I was puzzled by the year all the player characters were thinly veiled Red Sox team members, though.
