Good thoughts, but Maria does still appear quite often. Susan and Bob are the ones we see less frequently. As for the Fix-It Shop, it has been seen a few times this season, but only from certain angles. I am hoping we'll see Maria at work a few times next season. About the laundromat, I have noticed we see Leela there, more often than we see Maria at the Fix-It-Shop. I guess since she's a new character they are giving her more airtime. I see what you're saying about Hooper's though. It does seem like Chris is seen working there more often than Alan, but as far as I know Alan still owns the place. Chris is just an employee. B & E's Great Adventures are okay, but I would like to see more of the puppet versions of the characters, either in new skits or old skits. Hopefully, they'll have some of those next season too.
By the way, on a new subject. I finally saw the Pat Waburton clip. I could see him interacting more with the Muppets. I can totally hear him shouting:
'SUPER GROVER, I NEED PANTS!'
In case you don't get that, I'm referring to a line he once had on 'Kim Possible.' : )
