Near the end, after Patrick asks if he's going to grow "man boobs", he puts the soy dog up to his mouth, but in the next shot his hands and the dog are nowhere near his mouth.
Walter uploads a picture to the dating website that is supposedly of him 10 years younger with hair. About 10 years ago, the actor who plays Walter (Larry Miller) also starred in the film "10 Things I Hate About You" (1999). In that film, he was already quite bald.
The blindfold Joey puts on Bianca covers her entire face including her mouth, but in the next shot her mouth is uncovered.
Goof: When Joey comes over, Walter says to leave the door open in Bianca's bedroom. In a previous episode (Episode 6), we saw Walter totally remove the door when he found Bianca and Dawn doing an inappropriate webcast. Looking at how Walter behaves, it's unlikely the door would have been re-attached anytime soon.
At the end of the ep Mr. Stratford is wearing a University of Virginia sweatshirt. In the movie the character went to the University of Washington.
Goof: As Dawn is being carried by the people at the party and she says, "Oh, my God, guys! Don't drop me.", her lips aren't even moving.
