Continuity mistake: When Alan and Charlie are watching Judith take off her clothes on the monitor screen, Alan takes the newspaper he has in his right hand and puts it in his left hand to turn the monitor off. The next shot shows Charlie walking into the kitchen and Alan looks at him but now the paper is back in his right hand.
Other mistake: When Jake says "hey dad check it out you can see my room on here" he says it before he has opened the webcam. Could be explained that he could see the program running on the taskbar but as is already listed it's not on the taskbar. (00:20:00)Ssiscool
