Kyaputen Tsubasa (1983)

The Brothers Tachibana - S1-E22

Character mistake: The Tachibana twins' play leading to the second goal is called by the commentator as "on the limit of the offside", but that does not make sense; there are a bunch of players in front of them, it does not come close to being offside. (00:06:50)

Where Is the Rival? - S1-E5

Trivia: When Sanae starts waving the flag she made for Tsubasa, in the background you can see a couple of grossly disproportional characters most likely drawn as a joke by some animator, and even the Road Runner. (00:14:55)
