Revealing: Season 3, Episode: "Strange Days" When the guys are talking to Ari via cell phone from their black SUV, if you look at the black area between the front and back windows, you can see the reflection of the camera filming the scene from outside the vehicle.

Other: Episode 407, "The Day Fuckers": When Turtle and Drama are looking for potential sex partners on the Internet for Turtle, they spot a link for the "furry." Turtle starts dialing her number on his phone, but neither one of them ever clicks on the link, and thus, there is no way he could have known her number.

Visible crew/equipment: In just about every scene of the show where actors are wearing sunglasses, the large lighting equipment can be seen.

Deliberate "mistake": Twelve seconds into the intro, the shot of the store with the name Adrian Grenier above it is mirrored. Notice the reversed lettering in the signs.
