Type of show: Comedy Central half hour comedy set in Vermont*
Title: (Needs working title)
Character: Old Country Doctor who has a daughter named Maple. Not Mabel.
Catch Phrase: "It's the Thigh Huctose Porn Thyrup!"

*Not Vermontist. Love to the Vermontians present. I've visited. You must admit there is a certain vibe.

Thank you, Atom Eyes, for engaging my imagination for a day.

Thigh Hutcoe Porn Smyrrup is better. Also there are pygmy goats, at least one of which is voiced by an actor, just the goat thoughts.

The title of the show would probably be just the last name of the doctor (think "Becker"), who'd have to be someone semi-famous or famous 20 years ago.

Like "Birch" or "Porter" or so forth.

rainbaby, your show is starting to scare me. It's a shame Tom Poston is dead, because he would have been a perfect fit for your Dr. Birch/Porter. As for living actors... hm. Maybe the guy who played Frasier's dad?

James Cromwell.

In my mind, he is a secondary character. Maybe Maple and her partner Kathleen anchor it?
