Kevin's crush Lisa Berlini guest starred in episodes 5 and 6. Were there any other episodes she was in and has Kathy Wagner appeared on other shows?

She was mentioned in one episode from, I believe, the third/1989-90 season. Paul came up with a "Lisa Berlini poll." I can't remember the title, but there was a scene with Winnie and the cheerleaders out on the football field, and the Lovin' Spoonful's song "Did You Ever Have To Make Up Your Mind" played in the background.

"Old" thread, I know...

But the scene when Lisa told Kevin that she liked him "as a friend" was one of the funniest scenes in the show... it was great the way they stopped the film when she said "I really like you Kevin...as a ... ". And then adult Kevin's narration starts... that was great!

No she was never seen in the show after season 1 episode 6, she was mentioned but never seen in the episode where paul has a crush on kevins mother in season 3.
