I've watched all the episodes so far, this is my first comment on one.
First, the good. I like Mr. Yee. He's a good addition and the only cast member I actually like alot.
Now the bad. The animation is awful. None of the characters actually walk, they have one expression for every single thing and it's all around extremely poor. Please consider at least attempting to make it better.
I dislike the rest of the characters because they are cliched and poor in terms of actual character. The short, pushy boss, the slacker, the gamer girl, the nerd, etc. These are tired, overused cliches. Diversify the cast, make them your own! Don't just rely on tired sterotypes!
The jokes are overall bad and bland. If this is supposed to take place in the mid 80's, early 90's, then they'd be alright. They're still groan-inducing, however, because we've all heard them before. Try making up some new material, stuff that hasn't been done before (at least not in a mainstream aspect).
If this is supposed to take place today, however, these are nigh-unacceptable references. It only makes the show seem extremely (extremely, extremely) dated and stale. We've made a few innovations since 1988, why not incorporate some of them in?
Overall, this is the best episode because of Mr. Yee. I actually like him! Keep it up with him! (please don't run him into the ground, though)
