I would agree. It's time to end the show. It's been on so long that if you see real old episodes it's like watching a time-capsule, since so much of the humor was topical or revolved around pop-culture trends of the time.
As for the Muppets, I think Kermit sounds a little off but the guy they have doing Miss Piggy now is bang on. I never thought they could ever find someone who sounds like Frank Oz, but that guy (Eric Jacobson) is an amazing mimic. Not that Frank Oz is dead the way Jim Henson is, of course, but he doesn't do much if any Muppet work anymore.
