6. George Takei
At six we have George Takei, another member of Howard's fantasy. Having played Captain Sulu in the original Star Trek, he made his cameo in 'The Hot Troll Deviation'. He appears in Howard's fantasy alongside Katee Sackhoff. When Sackhoff questions Howard's homosexual tendencies he dismisses it, but is countered by Takei's quip "so you, say but here I am." He also appears in the car along with Katee Sackhoff offering conflicting advice over Bernadette, offering advice over what to do about women, because apparently he reads up on them. Takei provides a great cameo for geeks everywhere, and you can tell he's enjoying it all through his scenes, he can't wipe the smile off his face.
