I like the gag with the envelope best on this 'un! HA HA! It rolled me. Great ending to that sketch!! Sam, I felt, was just thrown in there and wasn't necessary.
Anybody ever seen the Orson Welles Show pilot with the Muppets on there? The whole thing is badly written and edited, unlike this (obviously), but my point here is that the way the Muppets were presented on the show were as if they were just edited and dropped right in. It was totally out of character the way they were performed and that was even performed by the original guys!!
At least From the Balcony sees the characters being performed correctly. Could stand to slow down on the speaking some though for S&W. Or, am I remiss that they actually did always talk that fast?
