Eric puts his sunglasses up on his head while talking to Vince's girl by the pool. When the conversation ends and she walks away the shot from behind Eric shows his glasses are down at his eyes. After she drops her robe the camera cuts to a close shot of Eric with his glasses still up on his head.
When Vince, Drama, and Turtle enter the room talking about Vince's new girl, Drama sits down and opens an issue of GQ. In the next shot, he is reading Sex For Dummies.
During his speech, the sherpa stands up and a little later he sits down 3 times.
Vince and E are in Scott "The Producer" Wyck's Mercedes smoking a joint which is approximately 1". When Scott passes it back to E, it's approximately 2" in length, noticeably longer.
As E is talking to Fiona he takes of his his glasses, but when she takes off her robe as she's walking into the pool, you can see E with them on. Then again when it's shot from a different angle, the glasses are off again.
