There's a Beta Theta Pi paddle on the wall during the opening credits of the sitcom "Coach" (before he moved to Florida). I don't remember any episodes that specifically mention him being a fraternity member, though. (Maybe that's a blessing.
) As I recall, none of the actors in the show were Betas; one of the producers saw the paddle somewhere, liked it, bought it, and hung the prop next to the door.
But what the heck, I'll take free publicity anytime.
