I did pregens for a beer and pretzels type of dungeon crawl once.
They all ended up with names like:
Don John Crowler (fighter)
Basil Le Vez (dwarf fighter)
Ilfindem Ferya (ranger)
Sehrgut Musikspieler (bard--I could get away with more if I didn't use english
I try to avoid that kind of thing in serious games.
I chose LoFan to be the name of my Monk. I'm not sure exactly how insulting that term is now, feel free to chip in on the issue if you speak Cantonese.
