I've got two scenes that alway kinda freak me out...
One is the classroom scene in 116 before Justin tells his teacher "fuck you". What is up with his freaking backpack? It's on, it's off, it's on, its off...AARRRGGG!
The other is the Pole!Sex scene 218(I think) and Justin's pants. I don't know maybe the director was doing some kinda visual thingy (kinda like the office scene in 308)but Justin's pants go up and down his ass so much it should make Brian jealous. Really throws me out of the scene.
