Isn't Bulma supposed to have green hair? And I just hope the dude with the baseball cap isn't supposed to be Krillin!
Update 5/15/2008: Scooper Tony correctly pointed out that Bulma has BLUE hair and that the dude in the cap is Chow Yun Fat and he's playing Master Roshi... I coulda sworn Bulma's hair was green! Maybe I need to adjust the color on my TV.
