Thanks roscoff. The idea was to do redraft after redraft, squeezing in as many gags as I could, but with a flat-sharing sitcom like this and the characters the way they are, I can't see much room for that, although I'm going to give it a bloody good try.
My next project was going to be an Airplane-esque spoof, which would allow me to do the above.
Again, thank you.
