I have a dwarf rogue named Crom Trews...but I haven't had a chance to use him on any missions, impossible or not. 

In a "variant earth" game we had a Frenchman who was called "The Frog"...Rika said:I once met a woman named Barbara Doll. Poor woman was in her 40s at the time.
Our worst in-game name was just weird. A fairly new player to our group once named his druid "Frog" his first spoken words to any of the characters were croaks.

The poor guy- as a Thri-kreen he couldn't even pronounce his own name.
