Whew... alright, here goes...
It needs work. No offense, but it does. Off-the-wall humor, okay... but this is a little too far out in left field. Even something this wacky needs to have some form of a consistent plot running throughout the episode, and this lacks such a plot. What you have instead is a sprinkling of subplots with nothing to really string them together. Even if you keep a subplot or small theme for a few minutes, remember that you need to have one central, ongoing plot to carry the whole episode.
The dialogue, I think, is your biggest weakness. The level of humor is mixed with swearing that only does not match it, but is all around distasteful. I'm not saying don't swear. I'm just saying to be mindful of the probable audience considering the humor you use. And some of the humor is a little funny, but sometimes it goes too over the top. I think it needs to be spread thin and used as a tension-breaker.
Your strength is definitely your ability to visualize. You seem to have a good sense of what you want to see in this episode. You know when to cut scenes, and what to show.
My advice to you is to spend a little time first in comic book scripts. Even if they're humorous, try writing a small comic book script or two with some form of a plot behind them to hone your writing. While you're good at giving me a visual (aside from a lack of character descriptions and setting details, which need to be listed at least before the script begins or something), your dialogue feels a little weak and underdeveloped, and I have to wonder if you're ready for TV scripts yet. That's why I recommend moving to comic book scripts for practice, because in my opinion, comic book scripts are a writer's stepping stone into cartoon show scripts. That's how my friend and I went about it, anyway.
