Sheila gets prank calls all the time, but that's probably due to her family's history of odd names.
Her brother's name is Seymour Butts, her dad is Randy Cox, her other brother is named Michael Hunt (yeah, I know, they all ended up with different last names, I told you they were odd), and her mother is named Brownie Shytles.
As for Sheila, she changed her name from the original, Fannie Licker.
(all this really started with her grandmother... Dixie Normus)
