Showdown at the Crooked D (S03E05)

Kim visits her uncle's ranch in Montana with her father and brothers, and Ron tags along, hoping for a relaxing getaway. Meanwhile, Dr. Drakken organizes a convention for the world's brightest minds, using his "silly hats" to render them foolish in a bid to claim the title of the greatest genius. Once again, it falls to Kim to thwart Drakken's plan, but she soon realizes she might need her family's support, particularly her cousin Joss, who looks up to Kim as her idol.
