#RPGaDay 17th - Funniest Game You Played

So, I've played Paranoia and that's certainly the silliest game I've played.

But the funniest game story I've got was from an old Champions game. I don't remember the name of the team, but we were a pretty standard pickup group of super-heroes that defended Houston against super-villains. My character was Dr. Jurassic, a paleontology grad student who had an accident with a velociraptor fossil and a Kirbytech DNA gizmo. He could turn into a Utahraptor (because as dinosaur experts will tell you, the raptors in Jurassic Park were way too big, except that after the movie was made, they found raptor skeletons that were the "right" size). So he was a big scary dinosaur with sharp claws and teeth. Another player was "Cue", who had a magic pool cue (or maybe she was a mutant and it was a power crutch, I don't recall), and she could make pool balls appear in mid-air, and she's shoot them at bad guys. Different pool balls had different effects.

So, some Inuit critters from the spirit world were making trouble and we were going on this journey through the spirit world to stop it. At one point, our spirit guide tells us that we're about to face this nasty creature, but it'll leave us alone so long as we don't laugh at it. It was magically funny-looking or something, but as long as you didn't laugh, it'd leave you alone. Now, the GM was intending for us to make EGO rolls to avoid laughing.

But Cue's player and I just looked at each other and, for whatever reason, just started laughing hysterically. The GM rolled his eyes and said "okay, I guess we go to initiative them."

Runner Up: It was a big epic 2nd Ed D&D game. One of the players was a Drow Ranger who was Destined to Kill Lloth. We'd gone on a huge quest to get Spiderbane, the artifact sword Also Destined To Kill Lloth. We fought our way through the Demonweb, smashed up stuff in the big robot spider castle thing, and burst in to the throne room. "Darkmover" (the drow) raised his sword and swung.
And promptly fumbled. The sword flew out of his hand and across the room. We scramble to get the sword to him (because only he can wield it) and he swings.... and fumbles again.  We get him the sword AGAIN and this time the wizard casts "Glue" to make sure he doesn't drop the damn sword again. We won, eventually. Darkmover started making criticals instead of fumbles.
