Fuzzy Bunny starred in an educational video entitled Fuzzy Bunny's Guide to You Know What starring Troy McClure. In it, we see lots of horribly dated 1970's references, including a sign promoting Bob Denver, an ice cream social, and of course Fuzzy's sextoy Fluffy Bunny wearing a Tube Top. As the money shot is shown over porn music, the kids all shout "Ew!" and Ms. Krabappel remarks, "She's faking it." Judging by the fact that Fuzzy gets married under a chuppah and breaks a glass to make the marriage official, we can conclude that Fuzzy is Jewish.
Just another obscure Simpsons reference that no one gets to brighten your day.
