Corrected entry: Here we meet "Zack", Justin's nerd friend. However for the rest of the entire show, he is called Zeke.
Corrected entry: We know that the Russos have kept Dragon. But in later episodes, he is never mentioned or seen.
Correction: In the episode "Max's Secret Girlfriend", Jerry asks Max "Is there anything you didn't tell her?" (meaning Max's girlfriend, Nancy, after he told her that he was a wizard) to which Max responds, "Yeah, I didn't tell her about the dragon dog because I still have no idea what happened to that."
You Can't Always Get What You Carpet - S1-E6
Corrected entry: When Justin takes Alex flying on the magical carpet, over the stadium, the ball hits Justin's head and falls to the ground. We all see it fall back, so what does Jerry mean when he tells Justin there was a baseball that never fell down?
Correction: Watch as the ball hits Justin, it actually falls to the left of him. Jerry says that the ball never came back down because the ball didn't fall back into the arena, so he never saw it fall.
Corrected entry: Harper takes an apple off of a stand, causing them all to fall to the ground. Watch carefully and you'll notice that the stand is tilted downward and the front side is latched and released, which is what really causes the apples to fall.
Correction: Many fruit stands are tilted down. Harper is that unlucky that by picking up one apple, the latch that she didn't even touch would break and all the apples would fall.
You Can't Always Get What You Carpet - S1-E6
Corrected entry: Jerry says that there was a flyball during a baseball game, and the ball never came back down. But while Justin and Alex were flying the magic carpet, the ball hits Justin and then comes down.
Correction: Yes, but when the ball hits Justin in the head, it goes to his left. So Jerry means that it never came back down to the field.
The Crazy Ten Minute Sale - S1-E1
Corrected entry: Alex and Harper say that Gigi's name spelled backwards is Gigi, but it is really Igig.
Correction: Yes, but when you say 'Gigi' it sounds like 'gg' so when you say it the name would be the same backwards or forwards.
Correction: Later in the series Zeke Beakerman makes a reference to this episode when he was called Zack.
