Times She Breaks The Fourth Wall
In the episode The Rhodes Not Taken, we find out that she played Sally Bowles in CABARET once.

In the episode Furt, she claims that she performed with Sue's mom, Doris Sylvester (Liza Minnelli was actually on The Carol Burnett Show twice).

Schumacher's first name is Lisa, but she is portrayed by Liza Minnelli (a tongue-in-cheek reference to her song, "Liza with a Z", in which she sang "It's Liza with a Z, NOT Lisa with an S!").
