We are fond of the extreme in cheese!
Ex-roommate has had a couple of Paladins in the same world of our GMs design: Hanover McGroin and his grandson Philip (also a McGroin)
My two cheesiest have been my Bard - Sam Goody and a Rogue/Arsonist named Burne Hibachi
My fave, though, is my current char. He is a Halfling whose parents left him, as an infant, with a Tavern owner while passing through town on a dangerous mission of some mysterious sort. They told the tavern owner that his name was Roscoe P. Tosscobble. To this day he doesn't know what the "P." stands for, but because of his everpresent backpack containing all of his possessions (abandonment issues!), all the townspeople took to calling him Pack.
