Some big fans of Linda are probably aware of this, and I saw Brian Damage mention it, but Linda was on season 4 of The Muppet Show on the episode where it's Kermit's birthday, and she also was 1 of the star cameos in 1984's The Muppets Take Manhattan. In fact, the book of "Of Muppets and Men" has some memories from Linda on what it was like to guest star on the show.

I've actually always thought she was quite sexy as the doctor in Manhattan. Just the way she spoke so soft and gently handled Kermit, it was almost seductive in an odd way. LOL!

Yes I do remember when iss Lavin was on The Muppets
