Apartment Neighbors Living Like A Sitcom

Would you ever consider finding not a roommate, but a neighbormate, with a mutual agreement to live your lives like a sitcom, constantly barging in on each other?
Ever since Seinfeld this idea has really appealed to me. I want a neighbor that just swings my door open and eats my food and tells me about his friend that knows someone who sells mink hats.

Am I crazy? Like pancakes, would this arrangement be all exciting at first, but by the end I'd be sick of it?

Does anyone else find that idea appealing?

I had a landlord that lived next door once. He thought we had this agreement. We didn't.
