I watched this in the late 90’s but my guess would be it came out in the 80’s. Unfortunately I only remember one strange line. A nasally-voiced girl (or possibly a woman acting like a childish girl) is wearing a frilly dress and says something along the lines of “sometimes I put alka seltzer in the toilet… I like to watch them bubble”. For some reason I thought it may have been the Incredible Shrinking Woman but after watching it isn’t. But it had similar vibes and the woman/girl may have looked kind of like Lily Tomlin? All I know for sure is the thing about the alka seltzer :/ Help!
The first thing that comes to mind is Fran Drescher in a sitcom called The Nanny.
Night Shift?

Found it! Well my mother did. Lily Tomlin did a bit on the show Laugh In where she dressed as a little girl in a big chair.
Correction: After some research I discovered it was an Edith Ann bit included on the TV version of The Incredible Shrinking Woman, but not the VHS or DVD version. Solved
Glad you found it and thanks for letting us know!
