Disturbia - Mic?
In the scene during Ashley's party where she goes into Kale's house to try to turn off the music he is blasting over her party music, pay close attention to the part where he is admitting the things he has learned about her while he has been watching her. You can see the mic above Kale's head almost the entire time. Even funnier is when the camera man notices and jerks the camera up. This had the whole theater laughing.
