I remember even the lesser known and seen Muppets were seen at least with one celebrity. Wayne and Wanda were seen with Connie Stevens. Nigel the Conductor asked Twiggy a question and Muppy was seen with Twiggy too. Digit and Leon got to be seen with Bill Cosby in that special Cosby Show episode. Vicki was singing with Smokey Robinson. Lindberg had a conversation with Ted Danson. Thor did a scene with Kathy Najimy who played a DMV worker in Muppets Tonight.
