"This device"

I started to plan a new dialog sequence! I found a clip I felt pretty entertaining. It's a clip from "40 Year Old Virgin"

Here are some thumbnails for the dialog sequence. I separated it in three shots. First shot is sort of an establishing shot with a clerk coming in and stealing a phone from the hands of a customer. Second shot is a 3/4 view favoring the clerk fiddling with the phone. Third shot, reverse view, 3/4 view favoring the customer. The clerk starts to film himself with the phone. The last shot is basically a view from the camera on the phone.

All comments welcome!
Thanks
