I do not think I have ever seen Young Frankenstein.

I remember her from "Head" and Star Trek: Assignment: Earth" which was an episode Roddenberry hoped was a plot for a new series. Evidently even if got go for a series she would not sign up for it.
For the Monkees movie Head, Jack Nicholson, who wrote the script, chose Garr as a woman who gets a snake bite and begs, "Quick, suck it before the venom reaches my heart!" This would become Garr's first-ver onscreen line.
