Revealing mistake: Haley's pregnancy pad is visible when she raises her arms while lying on the table. (00:21:15)
The Brothers Tachibana - S1-E22
Revealing mistake: In the very first move by Hanawa, Misaki and Tsubasa fold back before the twins' dynamic advance. Due to an animation error, Taro Misaki's hair in the wide shot flickers of a different color several times. (00:12:40)
Revealing mistake: Right after TJ and friends are looking at the "thermometers" of cans, the Ashleys have at least 4 crates of cans that they bring in on forklifts. However, the end result is 4,362 cans for the Ashleys. This may seem kind of picky, but I think there was more cans than 4,362.
Suggested correction: This is literally just an assumption, and nothing else. 4,362 is a pretty huge number, and with the amount of cans that we see the Ashleys collect in the episode, combined with the amount of cans that they and the rest of Miss Furley's class collected off-screen, it is perfectly believable that Miss Furley's class would end up collecting that amount of cans.

Revealing mistake: When Coach Norris matches Mark's dunk in their game of HORSE, you can tell that she uses a trampoline or some other kind of apparatus that's off screen to assist her in her jump.
