Hiya Hellisen!
Welcome to the Muppet Central Forum!
First of all, there are no silly questions. Actually there are, but those are the ones we love!
The Muppet Show was on the Hallmark Channel up until about a year ago, but I don't think it's being broadcast anywhere at the moment. As to why....that's a tough ball to call. I really hope someday soon it turns up on something like TV Land--in the past it's been on Nickelodeon and a few other channels.
Really, I don't have any answer for you, except to say "yes, with 500 channels out there, The Muppet Show should really be on several of them."
Hopefully this will be fixed soon.
Welcome!
