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)
Continuity mistake: When Ned is attacking Mike with the sword and then skewers his suit jacket, as soon as Mike fumbles out of the jacket both of his long shirt sleeves (one of the cuffs hangs out of the jacket sleeve) are suddenly folded up on his forearms, between shots. Additionally, the dangling left shirt sleeve cuff repeatedly moves in and out of the suit sleeve, and even after the jacket is discarded the cuff folds up, down, back up and so on. (00:19:20)

(Visible on DVD fullscreen.) (01:25:50)
Continuity mistake: When Mike comforts Maggie after her breakup with Stan, when he stands up and says, "I wanted to invite you to my party...," Mike holds his backpack in his left hand just before it cuts, but next shot his empty left hand is up near his face. (01:10:00)
Continuity mistake: When the "Nedmobile" pulls out of the driveway to head to the courthouse, we see Glenn, the crossing guard, at the corner and the entire sidewalk to the right, from the driveway on down. When Ned stops, in the shot from behind Glenn there are two trees at the curb, which were not there in the previous shot. (Visible on DVD widescreen.) (01:21:15)
Continuity mistake: When Mike begins to voice his thoughts in Health class, as he says, "It's called 'making love', isn't it?" Maggie is holding the pencil up in her hands, but next shot the pencil is gone. (00:46:20)
Continuity mistake: Before the start of the last basketball game, when Ned (wearing a "cloak of invisibility") calls out to Jane, the people surrounding the seated principal change depending on the angle of the shot.

Continuity mistake: After Ned shows up for the '89 team photo, in the shot facing the team when he and Mike are walking over to their places, players 23 and 24 are kneeling as Mike passes them. In the next shot facing the photographer, those two teammates are walking behind Mike just before kneeling. Coach Murphy also moves from beside the last teammate to behind and has thrown the ball to Mike, between the shots as well. (00:01:50)
Continuity mistake: Near the end, when Mike is warming up in the gym, just as Coach Murphy says, "Hey, Gold," as he's walking in there is one basketball on the top tier of the rack (the last ball Mike takes is from the bottom tier), but when Coach Murphy says, "Got a little inside info...," the top tier is empty. (01:28:05)

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.

Continuity mistake: When Ned falls over the upstairs banister in his house, Mike leaps over and lands on the rug beside Ned's head.

Answer: I've not seen the movie, but an ex-wife would be closer to her ex-husband than a coach to his old student, no matter how good.
