It is so bizarre to see people getting their teeth whitened in the mall. What makes it even funnier is that their lips are all pulled back like they are standing in a wind tunnel, they are drooling and everyone walking by is guaranteed to be staring as they go by. The entire thing is very entertaining to watch.
This one has a TV in each booth and they are playing Christmas movies of all things. It would be funnier if they just had a video camera pointed on the people walking by so you could watch them watch you. Even better… put a lens on the video camera to make everyone walking by look short and fat!
