"Deeper Throat"

I haven't seen any of the episodes, but it doesn't sound like something that I'd be interested in. Unless of course she's actually performing, which doesn't seem likely, even for Showtime.

The movie itself,'on the other hand, might be worth watching. Anyone seen that?

Well, there's a complete dweeb who walks around and tells everyone he's a VP. And yes, they show a clip of him testing out a would-be porn actress' oral skills on the casting couch.
