How does the 3D work? 

I've never been to a 3D movie in my life, are the current 3D's like the ones from years ago and a person has to wear the special 3D glasses in order to view the 3D effects? 

Just curious, my weird sense of humor is sort of curious about the latest Jacka$$ movie.  Yeah, it's juvenile, and most of the time it probably would bring out a sigh of disgust from me in how stupid it is, but the way those particular guys do those extremely stupid and ridiculous bits, ... well they usually make my sides hurt really bad from laughing so hard. 

Just a good thing they don't do that crap right in front of or around me, ... or to me.
