Francine Simpson

Francine "Mother Shabubu" Simpson (born Frank Simpson) is Homer's cousin, but what is known about her can only be pieced together from what Homer has said about her.

History
While discussing the possibility of moving from their small apartment due to lack of space because of the arrival of Lisa, Homer says that Lisa can have Bart's room, and Bart will sleep with us until he's 21. Marge asks "Wouldn't that warp him?" And Homer replies, "My cousin Frank did it, and he was fine." He then says that Frank became Francine in 1976. He then adds that Francine joined a cult, and that Homer thinks Frank's name is 'Mother Shabubu' now.
