Brown, as a satirical valley-girl version of herself, would often introduce,"jump into" (by blue screen) or speak after a video with negative, scathing comments about the artist.

Teen stars like Tiffany and Debbie Gibson were frequently mocked along with Samantha Fox and Paula Abdul (questioning her tap dancing and talent).

A notable example: after playing a Sheena Easton video, Brown quipped that "maybe we should all sleep with Prince so he'll write songs for us."

In another episode Julie provides running commentary as Tawny Kitaen as the Whitesnake video, 'Here I Go Again' plays, saying "Here's my boyfriend David Coverdale...

", and in "The Nuclear Show": "There's more to life than watching MTV, shoplifting and having meaningless sex with people you don't know or care about.

She even got her chance to show the video for her 1984 song that MTV refused[citation needed] to air, "The Homecoming Queen's Got a Gun", in the episode 'My Evil Twin' where her "sister" Debi (the "Homecoming Queen" from the video, who was "shot" to death, but survived) escaped a mental institution to seek revenge on Julie, and succeeded.

Easton later appeared on the show disguising herself as a maid to make Julie go crazy in return for all the times she's made fun of her.

Toward the end of the series run she adopted the "Eco-Gal" persona and along with "Recycle Man" they drove around looking for wrongdoers (like spotting Stevie Nicks twirling around in her driveway and throwing her mail all over the ground).
