That's true. I've always wondered how those retarded looking spoof movies made any money. Then i went to the movies when the preview for one of them came on, and about a quarter of the dumb ass people were laughing. Just enough to make some profit.
to some people it's a deep habit to go the movies. It's as natural as shiting, eating pizzas and drinking coca cola. They always tell you every single movie they ve seen was great, only say its crap if the general opinion is that the movie is indead crap. Basically they re sheep, the ultimate followers. Being led, conditionned 24/7 365 days a year with 0 hability to think by themselves. Most of the the time they also watch A LOT since childhood and have been conditionned to do so by their own parents and grandparents who constantly watch TV. As you said it, they laugh but they dont even know why. Because they are suposed to, so they do. They re like robots, answering automatical stimulies.
