Other: During this whole episode, Jake calls his mothers boyfriend Greg. But in the 4. season when Judith is marrying the guy, he is called Herb. We know that it is not two different persons because both persons last name is Melneck, and they are both Jake's pediatrician.

Continuity: Near the end of the episode Alan says, "Well the point is you brought Jake into the relationship too soon." Just before he says that Judith's left arm is laying over her right and in the next shot her right is over her left.

Continuity: When Charlie and Jake walk in on Judith and Alan kissing, Charlie says, "C'mon lets go boat shopping" to Jake. As they leave Charlie shuts the door twice.

Revealing: When Alan is banging on the bathroom door, the entire set is shaking.

Continuity: When Charlie and Berta are in the kitchen talking, Charlie sits down and places his coffee mug on the left side of his plate. A few shots later he is seen placing it again except this time on the right side of the plate. Then just as Berta exits the kitchen, Charlie's mug has now switched sides again, being on the left side of the plate.

Continuity: 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.

Continuity: When Charlie picks up Jake's shoe in the beginning it is facing up, when Jake takes it from Charlie's hand it turns itself upside down.

Factual error: Three times during the episode, when Jake is playing his DS, one of the characters plugs in the headphones. However, the cable is inserted into the socket for the charger on the top of the DS, instead of the headphone socket, which is located on the bottom.

Plot hole: Jake explains about what happened in the house at the weekend in a report. How could he know what Uncle Charlie and Alan are doing if he is not around?
