Continuity mistake: Tara is sitting at her desk and tells Max they will have sex the following night, and she teases him that she "Might even bring some props." Right as she says this line, the camera cuts. In the first shot, she has one pencil in each hand, but in the second shot, suddenly both pencils are in her left hand. The position of her hands changes between cuts as well.
Continuity mistake: When Marshall and Jason are speaking in the hallway near the end of the episode, watch the background. The extras playing the students often do not match as the shots cut back and forth. (Most obvious being that students walking down the hallway, who vanish and appear when they should not).
Continuity mistake: After "Alice" washes out Kate's mouth with soap, watch Kate's face. At certain times in the rest of the scene, there's a bit of soap-suds around her mouth, while at other times its gone. A red smear also appears on her face between cuts after she comes back inside of the restaurant to ask for an application.
Other mistake: When Max drives Charmaine to the surgical clinic, watch the background. In the first few shots, they are driving through some sort-of suburban neighborhood if you look out the windows, but suddenly when the camera cuts outside of the car, they're in a parking lot for the clinic, nowhere near the neighborhood they were literally just driving through. There was no time-jump as they are having a continuous conversation through the entire scene.TedStixon
Visible crew/equipment: When Tara gets into her car after seeing her therapist with Max in the beginning of the episode, watch closely when the camera moves up to the side of Tara's car. If you look at the bottom-left corner of the screen, you can see the top of a crew-member's face and some camera equipment reflected in the driver's side window right before the scene changes.
