Question: I've heard that the original name for this show wasn't "The Powerpuff Girls" and that the original name had to be censored. Anyone knows what was the original name of this show and why it was censored?
Answer: The original name of the show was "The Whoopass Girls", so called because their father accidentally spilled a can of whoopass into the sugar, spice, and everything nice. The reason that this was changed should be obvious. You'll never be able to sell a bunch of toys to children if these toys have the the word "whoopass" on the front.
Chosen answer: Her agent/manager negotiated a special billing as part of her contract. It distinguishes her from the rest of the cast, probably when she became a producer on the show.
