Okay, I watched this in the late 90s. My guess is probably came out 80s/early 90s… And unfortunately all I know is an odd brunette girl (or possibly a childish woman) says something along the lines of “Sometimes I put alka seltzers in the toilet… I like to watch them bubble” in an incredibly nasally and annoying voice.
Help, please and thank you!!
Solved.
