When Norris and Barry walk into the bar in the western fantasy you can see the two glasses of milk that they order on the bar before they order. They disappear in the next shot and then reappear as the bartender hands them the milk from under the bar.
During Barry's daydreaming while he's in gym class he's in a saloon, you can see the shots of milk before he and Norris order them when Norris shoots upwards at the man above, and disappear as they order them, and come back into shot when they're suppose to be.
The Inhaler that Barry uses is not a use-on-demand type inhaler, it is in fact a one-time daily use inhaler.
Boom Mic is visible. The scene in which Barry's dad has the conference with Ms. Chan, in her office, the boom mic is clearly visible at the top left of the screen.
The Frying Dragon team won the Weapons, Men's Fighting, and Breaking competitions and came in second in the Ladies' Kata. Yet somehow after that they manage to only be tied with Stone Dojo.
During the tie breaker part of the competition, when Randy is doing his second break, he asks for another brick. The announcer states that he is attempting a record breaking 9 bricks, but in the original breaking competition, Mr. Lee asked for started with 8 bricks, then asked for a 9th to be added, and when he breaks the bricks, there are actually 10 bricks in his stack. This should have been a record.
Seemingly the only advantage The Frying Dragon team acquired by winning the coin toss was that they got to pick their participant. This is meaningless since The Stone Dojo got to pick the event and pick their participant. Winning the coin toss meant nothing.
