This advertisement kind of reminds me of watching a Coca Cola ad that spreads kindness. They deserve props for combining an advertisement along with a prank that basically shows you not to judge a book by it's cover.

This took place in Kinepolis Cinema, Brussels which people thought they we're going to see a movie but were the actors unknowingly. YesFunnyYes is a comedy channel that is responsible for such a talented idea. Now imagine you walk into the movie you've been waiting to see but inside it is a fully packed house. Not only is it a packed house but it's packed with 148 bad boys all around with only two seats left in between all of them. Now some innocent couples were put to the test on whether they would stay for the movie or leave. It was surprising to see the outcome of this prank which led to a cheers with Carlsberg brew (the advertisement) in the end!

So the point of this prank is to teach you not to judge a book by it's cover.
