they didn't make last names. i know lets turn this into a thread where we think of funny last names!!!

tidus dickinson (he has orange skin just like david dickinson!!!)
rikku toy (she's so petite!!!)
wakka ginge (ok i'm sorry...)
lulu moodu (i should burn ur ass!!!)
yuna dances (just to drop a hint really early in the game. and heh, its true!!!)
kimahri fluffy (actually his 2nd name is ronso but this name is more suiting i think!!!)
auron smash (say it as auron in 3rd person . . . like the HULK!!! RARGH!!!)
