A Few Oddities
There have been a few oddities that have occurred in my game.
Back in college, two PCs/Players got into an argument. (It was basically a both in and out of character thing.) The group of PCs had been digging in the loose soil at the bottom of a pit with shields, trying to unearth something or other. The argument ended with the dwarf PC swinging on another PC with her shield. Combat ensued. The rest of the party quickly joined in. I finally had to shout over everyone to point out that the fight could NOT have started because the dwarf wasn't even in the pit in the first place. (She'd stayed out because the loose soil was over her head in places.)
Oddly enough, their reaction was basically to go "Oh" and go back to proceeding forward with the adventure as if nothing had happened.
The wizard PC who (for whatever reason) decided to try and use Polymorph Other on a fallen demigod the party was facing off against. He choose to turn the demigod into a guppy. A natural 1 was rolled on the saving throw. The demigod, still alive if having problems breathing, put up a darkness area. This resulted in a party of high level adventurers running around the darkened area stomping the ground as hard as they could in hopes of stepping on the guppy and killing the demigod.
This resulted in the wizard's later battle cry of, "I turn gods into guppies!".
And we just won't go into the time the dungeon (and the DM) when horribly wrong and the party ended up dealing with full-sized cartoon characters. (No, dear, that isn't a man in a big rat suit, that's the actually character...) *sigh* I really have no idea what possessed me. I plead insanity, stress, and frustration with the players.
For other gaming systems, I had a Shadowrun game I ran where the team was hired to deliver "a message" to a local gang. The group, punchy and feeling they outclassed the gangers too much, had their rigger drop them in the middle of the street. They then proceeded to sneak along the fronts of buildings - or where the fronts would be when there was an alley or something - like something out of a bad cartoon. They actually told the gangers who asked them what they were doing, "Shh, we're hunting wabbits." (Totally different group than the one attacked by a cartoon, I swear.)
In Star Wars, when trapped on a world and about to be arrested by Imperial forces, we came up with a plan to fake our own capture and then try and take over the Star Destroyer for our own uses. (I'm still not sure which is worse: That we tried it, or that it almost worked.)
