A Goofy Movie (1995)

Continuity mistake: When Max is running out of the school after successfully becoming cool. We see his friend with the orange mohawk at least twice. Once hanging from a statue, and another where he's reaching out from a school bus. These two shots are really close together so there is no way that he could have moved that quick.

Max: Dad... listen, about my directions... will you listen to me? I gotta tell you something, Dad.
Goofy: Why bother? I'm probably too stupid to understand anyway, right?
Max: Forget it.

Trivia: Ariel from the Little mermaid can be seen after Max gets in trouble, she can be seen on the right when it cuts to his friends, she can be seen again when Goofy and Max go to the hotel pretending it is water - she can be seen as a light stand.

Question: I have looked all over the web for the wav of the sound Goofy makes whenever he is falling, which he does at least once in every cartoon he is in. It sounds like 'yah-ha-ha-hooey.' I have never found it, so can someone point me to where I might be able to download it?
