The TV show "Would You Fall For That" is a hidden camera show that is based around seeing if they can get people to fall for situations they set up for them.  In this episode, they wanted to imitate what was done by the classic show "Candid Camera."  

In one of their famous tests of conformity, they had actors walk into an elevator with one person who isn't aware of what is going on.  Once they are in, instead of turning to face the door, as is normal, they all face the back of the elevator, leaving the one lone person who isn't in on it to decide if they are going to do what they feel is normal or conform to the group.  Watch to see the results.
