One guy in my group is famous for silly names.
Last summer he was Jaun Danger Messerschmidt ("Danger? Danger is my middle name!"), a Sprite rogue.
This summer he's Jack "Blinky" Caggen, a human with three eyes.
In the other game, he's Cliff Jumper McCraken, wildmage.
His NPCs are noted for having interesting names as well, such as Dr. M (store brand Dr Pepper), and the famous Woo brothers: John the Baptist Woo and Jesus Woo (pronounced in the spanish "Hey-soos"). John Woo is a bard. They're dwarves, and despite the biblical, spanish, and asian-inspired names, they speak with heavy scottish accents.
You'd think that all the foolish names would detract from the game, but they don't. After the first few giggles, everything pretty much goes on as normal.
