I agree with everyone else who has said that presentation is important. Maybe the fact we are all saying means it might be worth listening to (though I admit the majority used to think the world was flat). Anyway, I digress. If you can, please sort out the caps lock more than anything. It's almost impossible to read when it's all in caps.
But I did try.
So, here's the verdict.
Firstly, it's incredibly hard to judge an excerpt without knowing where it sits, or what the sitcom is about. Next time, maybe consider giving us a short (one paragraph) introduction to describe the sitcom overall and what this episode is about. (e.g. if Cleese and Booth popped on here and gave us an excerpt for peer review, they might say "Fawlty Towers is about a snobbish hotelier who is always looking for a better class of guest, though he's kidding himself and he's really found his level. His efforts are often frustrated by his nagging wife and his inept Spanish waiter. In this episode a bang on the head leads him to behave inappropriately in front of some German guests.")
They'd write it better - but it gives us something to hang the excerpt on, if you see what I mean.
This leads me on to the main problem I had - I didn't understand WHO the main characters were, WHAT they wanted from life/the episode, and WHY they were where they were. I felt I needed to know what this episode was all about. Us comedy viewers need a bit of spoon feeding every now and then - if you do it with subtlety it doesn't feel force fed. Try watching the first few minutes of a few of your favourite episodes and I bet they will plant the seeds of a story very early on to hook you in. Your excerpt (admittedly, only an excerpt) didn't hook me, because I couldn't work out if there was a hook.
Another tip I'd give is making sure you describe every important action on the page, as otherwise we aren't going to get it. I've a feeling you might have something really funny in your head with the mumbled mime that's repeated several times early on - but unless you describe the mime in detail first time, it'll just remain in your head and won't be transferred to a script reader and then performers (and ultimately viewers).
Finally - some positive stuff. Some of the dialogue shows promise. I think you have a bit of an ear for the language of this group, but give yourself a chance to show it by formatting it as well as you can, and doing a bit of a polish on it yourself before showing it to anyone else. It isn't particularly funny so far, but I always think that's the least of a script's problems.
Good luck.
Thanks
