In the second season where Ned and Cookie made the school website better they made a school hall cam. but it got caught on a weasel and turned into a weasel cam. When Ned and cookie and seth powers (the b-ball player) are trying to figure out the password so they can turn the camera off, you can see the science teacher in the reflection of the glass window door who is supposed to be off camera, just standing there waiting. But literally a second after the weasel cam is in his classroom and shows him sitting down in an entirely different room picking his nose. after he notices the camera is on him and the kids do, the kids panic as he walks in the room.
