The Karate Kid (1984)

Revealing mistake: When Daniel is running from Johnny and his gang after the bathroom incident at the dance, there's a lot of fog outside. If you look at one of the trees in the background, you can see that all the fog is being puffed out from behind the tree - obviously a fog machine.

Daniel: You're the best friend I've ever had.
Miyagi: You... Pretty okay, too.

Trivia: Ralph Macchio has almost no sense of smell at all. Just for fun, he makes it a point to smell something at least once during every movie he's in. In this movie, he smells a french fry at the restaurant, and he smells his underarm before approaching Alli.

Question: I read that there was supposedly a deleted scene which happens during or after Daniel's fight against Dutch. Namely, after Daniel scores a point, Dutch gets so angry that he tackles him, causing him to get disqualified in the process. Is this true that this scene existed?
