Where to start
Your animation skills are there, I can tell, even if you dont use them much in this flash. The drawings are, as usual for your stuff, excellently done and polished. The sound quality and voice acting are top notch and really really professional sounding.
However, you fall short when it comes to humor. I wouldnt really call any of the stuff "unfunny" because all the skits warrant a small half hearted smile, but just something about the way you try to execute the jokes is terribly dry and slow, and just overall unsucsessful. I felt like I was watching paint dry (and in a sense I was! :D).
My favorite skit was by far the crudly drawn "yep" restaurant scene. I felt that it was by far the most creative and most intresting, the others just sorta droned on and on with a complete lack of the humor that could be brough forth in a skit that drags on like that (where the fact that it takes so long is basically what makes it funny).
You have outstanding animation, drawing, and voice acting/sound editing skills so maybe try your luck at more serious flash, because also basing this on seeing your other entries, you stumble when it comes to comedy.
