Uncle Arthur (Paul Lynde) in "Bewitched"
Natty suits with kerchief. Flamboyant hand motions. A constant giggle. And more interest in Darren than Samantha. GAY.

"Maude" (Bea Arthur)
The gravelly voice. The helmet hair. The kaftans and beads. And she could whip Archie Bunker's ass with one hand behind her back. GAY.

Bosley (David Doyle) in "Charlie's Angels"
The lisp. The scarves. The complete lack of sexual interest in the Angels. And he cowered in the corner while the ladies did all the dirty work. GAY.

Felix Unger (Tony Randall) in "The Odd Couple"
Fussy. Obsessive-compulsive. Clean freak. Always wore a crisp tailored suit. So he had a wife. She kicked him out. Why? GAY!

KITT in Knight Rider
Sensible. Stylish. Fiercely protective of Michael. And he spoke like Prince Albert at High Tea. GAY. Gayest car ever. Even The Hoff knew it. Right, Hoff? See.

Velma Dinkley from "Scooby Doo"
Just look at her. I have no doubt that behind closed doors, she'd throw off the glasses, whip off the turtleneck, shake out that sensible hair and eat you alive, If you were a girl, that is. Strictly vagitarian, trust me.
