There was a Scientology reference on the 10/29/04 episode (repeats throughout this week) of Bill Maher's HBO show "Real Time." Bill had guests Richard Belzer, Wesley Clark, and Kevin Costner. Joining remotely was Ann Coulter.
This was a heavyweight lineup by anyone's book, (hey, Belzer married Harlee McBride which means he rates highly in MY book). It probably had a large audience.
Anyway, toward the end of the show there is this segment called "New Rules." Here is one from this show:
[begin excerpt; Maher does all the talking]
"New Rule: Scientology makes you fat.
[Image appears: pudgy headshots of Kirstie Alley, Lisa Marie Presley, John Travolta. Title: "Diet-netics"]
[laughter and applause; reaction shot of Costner laughing]
Kirtie Alley, Lisa Marie Presley, John Travolta...fat fat fat.
L. Ron Hubbard went to the cupboard to fetch his old dog a bone...
[laughter and applause; Bill pauses for effect]
...but it was GONE because his followers SCARFED it.
Let's be honest: it's not a religion it's just an excuse for a bake sale."
