Page "Edna Krabappel" Paragraph 6

In Season 17 (" The Seemingly Never-Ending Story "), a flashback showed that Krabappel was in a serious relationship with Moe Szyslak when she first moved to Springfield, before meeting Skinner or even becoming a teacher.

She was about to elope with him, but then changed her mind when she met Bart Simpson, a student she believed needed help.

Consequently, Moe breaks up with her.

At the end of the episode, Moe and Edna are a couple once again, much to Skinner's jealousy when he catches them making out on school property.

In " Regarding Margie ", she and Principal Skinner are seen making love on a golf course.

Then he climbs off and she says, " Birthday is over, Seymour ," and lights up a cigarette.
