Other mistake: On the "Mario's Greatest Movie Moments" DVD of this series, from the main menu, go into the trivia game. The fifth question asks you about the Super Mario Bros. Super Show episode 'Count Koopula.' It asks you "What's room number that the Mario Bros. were put into in Koopula's Castle?" It's supposed to say "What's THE room number that the Mario Bros. were put into in Koopula's Castle?"
Grandpa vs. Sexual Inadequacy - S6-E10
Other mistake: Look closely when the clerk scans the books. Ueberroth is a brown book, and Al Gore's book is green. The book that sends the message to Al Gore is the Ueberroth book.
The Ringer - S1-E1
Other mistake: When Link and Zelda fight Ganon and the skeletons, 3 skeletons grab Zelda. Ganon throws a bomb at Link and Zelda. Link lifts Zelda and the skeletons are hit by the bomb. It explodes but only hurts them as they vanish, not fazing Zelda or Link what so ever despite being right above them. But a little bit later, Link bats a bomb at Ganon that is exactly the same as the previous bomb. This one explodes huge and destroys a cave. Two of the same bomb, no consistency of power at all.

Onna no koi wa snesouyo! Kakutou shintaisou de iza shoubu - S1-E12
Other mistake: When Akane and Ranma arrive to Furinkan High, it's 8 past 20. When Kodachi leaves, it's 8:35. 15 minutes is way too long of a time to have passed (and everyone would also be late for lesson). (00:01:50 - 00:04:40)
