Trivia / Diseasy Does It

• What Could Have Been:
  • Kenny originally had a more oval-shaped head, but the Cartoon Network execs felt that made him look too much like Arnold from Hey Arnold!.
  • Tom Warburton wanted Mark Hamill to be the voice of Professor XXXL, but the role went to Frank Welker instead. Hamill would later voice Stickybeard on Codename: Kids Next Door.
