History Funny / Underdog

** In part 1, a group of scientists are examining a gigantic stone, and one of them compares it to a cantaloupe.

The second scientist replies, "Maybe it's a ripe stone cantaloupe".

* Part 2 of "The Tickle Feather Machine" has the montage of four tests Simon performs on Cad to see what condition could prevent people from voting, so the two criminals can vote Simon for dictator with no opposition. All four tests fail. To elaborate, the first three inventions tested on Cad are all guns: the first one makes him sneeze nonstop, the second one makes him cry nonstop, and the third one relaxes his muscles so much he can't stand up. Nonetheless, Cad still manages to reach the fake voting booth and pull the lever every time. The fourth item is a big machine with robotic arms that turns Cad upside down, and it throws him down so hard he bounces on his head until he lands in front of the booth and his foot pulls the lever by accident.
