7. Edna's Sex Education Video
Edna is not very good at keeping her professional face on. It's a common hilarity to find her blabbing bitterly about past lovers, and before she slides a sex education tape into the video player comes this humdinger of a speech
"Class, in order to explain why your hormones will soon make you an easy target for every smooth-talking Lothario with his own car and tight jeans, I will now show a short sex education film."
The fun doesn't end there, with Troy McClure giving one of his finest of many video voiceovers "That night came the honeymoon!" and Edna gave her own most welcome of analysis from the back of the classroom while smoking a cigarette. "She's faking it" is arguably her best one-liner, and this episode, 'Bart's Friend Falls In Love', will be one for fans of the bitterest of school teachers to cherish. You almost get the impression that Edna would rather have just sat all the girls in the class round her desk and ran them through all her past boyfriends/husbands. That would certainly scare them into a life of chastity belts, and ironically may be more preferable than the video she showed which came complete with some funky porno Seinfeld-esque slap bass. At least the bunnies in the video, unlike Edna, wait till the honeymoon. So certainly, not the ideal teacher to be teaching your children about the birds and the bees, but in the twisted world of Springfield, Edna Krabappel is the most hilarious option.
