Well I know of a guy named John John and I hope his parents weren't cruel to give him the middle name of John.
There was a threat of naming my grandniece either Mercedes Lexus or even worse Summer Eve. What's worse, it was my sister trying to convince them! If you can find it, there's a song by Shirley Q. Licker called "Who is My Baby's Daddy?" to the tune of Billy Joel's "We Didn't Start the Fire".
When I first entertained the thought of running an OA game, one friend wanted a character named Ped Xing. He's also the creator of Joelarryndave, a pc run by him and his brother (one always worked so the personality changed as did the character's tattoo) tho I can't remember others offhand. Another member of our group had all of his characters, regardless of race, have the family name Farrell while the first name was from a basketball player. IIRC, his favorite was Hakeem Farrell.
I had:
Opec Johnson, whipwielding tombraider
Klaatu B. Nikto (kender)
Akuna Atata (yeah, it was a passing phase so no worries)
the short lived Rupert Ignacious Pendleton III (also a kender)
Humperdink H(umperdink) Humperdink III, a high elven lineman from my Blood Bowl team
Mozzell Toff (I think), wood elf lineman
the wood elf brothers, Lawrence, Darrell and Darryl Kowalski (My name's Larry. This is my brother Darrell and this is my other brother Darryl)
my Chaos team had beastmen named after diseases and warriors named after antibiotics I think
one Skaven team was named after cheeses while another was named after the Draconians
Oh, I had to give my rat ogre a name to strike fear into my opponents so the most fearsome name I could think of was... Buttons!
