You started off with a good concept, then...
The main problem with it was that...well... I don't think you were really in your characters. It just seems like you just aren't showing any enthusiasm at all. The jokes would have been alot funnier if your delivery was better. And is it really necessary to show us the studio audience? I think we kind of gather the situation before hand.
This could end up a really good, original series, just try giving your joke delivery a little more emotion and timing. Otherwise, it was fairly good. I still liked it.
