Jub-Jub

Jub-Jub is Selma's pet iguana. He was originally owned by Aunt Gladys.

History
When Gladys died, she left Jub-Jub to her sister Jackie (Selma, Patty, and Marge's mother) who was highly unattached to him and tried to stab him with a hat pin. Jub-Jub then ended up with Patty and Selma, and became Selma's pet.

Selma once said that Jub-Jub will eat her remains upon her passing (probably a reference to an urban legend about Vivian Vance and her cats). Jub-Jub is always trying to eat dead things, and once almost ate Selma's foot, because it was asleep. Jub-Jub also likes roaches.

Behind the Laughter

 * The name Jub-Jub was coined by then-writer Conan O'Brien. He often said nonsensical things around the office for no apparent reason, one of which was "Jub-Jub."
 * "Jub-Jub" may also be a reference to the poem "Jabberwocky" by Lewis Carroll, in which the narrator warns his son to "Beware the Jubjub bird."
 * Robert Kane-Vaziri of heavy metal outfit Black Hawk Dawn has a pet iguana named Jub Jub.
