Continuity mistake: When Mike grabs a lightsabre and shouts, "Ned, Ned, Ned, I'm telling you...stop it!...Now!" his arms are extended out with the lightsabre held aloft, and his tie hangs properly. It cuts to Ned turning on his lightsabre's glow effect, with Mike and his raised lightsabre in the foreground. In the next shot, as Mike's arms are still extended out, his tie is now dangling over his right arm. (00:19:35)Super Grover
Continuity mistake: During Mike and Ned's lightsabre duel, when Mike kicks Ned just after Ned says, "Covered by the local news," the chair in the kitchen behind him faces the foosball table (in the next room) with its back against the counter, yet in the previous shots that chair faces the front door. (00:20:20)Super Grover
Continuity mistake: When Mike swings his lightsabre and causes Ned to slam backwards onto the floor, Ned drops his own lightsabre onto the floor beside him, with its red glow pointing toward the front door. Next shot the lightsabre is turned the opposite way, with its red glow pointing toward the kitchen. (00:20:30)Super Grover
Continuity mistake: When Ned and Mike are fighting with the lightsabers, Mike hits Ned with his lightsaber and he falls to the floor. When you see the shot of Ned falling, look at Mike. He is only holding his saber with one hand. In the next shot, you see him with both hands on his saber. (00:20:35)Low Cow
Continuity mistake: During Ned's attack on Mike, Ned pulls the rug out from under his friend, after which the rug lies bunched up on the floor near the front door. As the scene plays out the rug's position changes between shots, particularly after Ned kicks Mike in the groin when Mike falls on his back with the rug under him. (00:20:40)Super Grover
Continuity mistake: When Mike returns to Hayden searching for the 'janitor', as he is speaking to the real janitor saying, "There's an older guy with white hair...," Mike's black sunglasses are in his left hand, but when it cuts back to the close-up it's back in his right hand. (00:22:55)Super Grover
Continuity mistake: While Ned and Mike are waiting for the school secretary to get off the phone (for enrollment), when Mike opens the folder the faked science fair photo is at the top of the pile on the right. In the next shot, there is a photo on the left leaning on the inside of the folder cover and the science fair photo isn't at the top of the pile on the right, but when it cuts there are no photos on the folder cover. Then Mike closes the folder, but next shot it's open again. (00:26:10)Super Grover
Continuity mistake: When Mike and Ned are in Principal Masterson's office and she says, "I think Hayden would be lucky to have you," she stands up and removes her eyeglasses, but when she shakes Mike's hand she is wearing the glasses, and next shot they're off again. Then yet again, when she sits back down she is wearing them (in the foreground), just before Ned asks, "Would the lady mind if I smelled it?" (00:28:50)Super Grover
Continuity mistake: After being accepted to Hayden High, when Ned says, "You always had my back in high school, if your spirit guide...," Mike's left hand is up at his mouth in the shot facing Ned. In the next shot Mike crosses his arms, but when it cuts his hand is back up at his mouth. (00:30:30)Super Grover
Continuity mistake: During Mike's first class (before Maggie walks in), when he's on the cell with Scarlet, who is asking where he is, a cheerleader sits down behind Mike and places her right arm up with her hand at her chin and her left arm is down. However, in the next shot when she asks Mike if he would consider a 10th grader, now it's her left arm that is up and her right arm is down, instantly. (00:32:35)Super Grover
Continuity mistake: In Mike's first class, when he sees Maggie walk in while on the cell with Scarlet, his left arm is either in front of him with his left hand up near his mouth, or his left elbow is on the desk with his head leaning on his left hand. The switch happens twice. (00:32:50)Super Grover
Principal Jane Masterson: You can plunder my dungeon anytime.
Ned Gold: I'll bring my longbow.
