Somewhere in the history of American cinema, someone (maybe John Waters?) decided that gross and profane and funny could all sit on the same park bench and start up a friendship. That was way back in the 1970s.

Today that friendship has moved on to total and committed "bromance." Check out two summer releases, "21 & Over" (opening tomorrow) and "The Hangover III" (opening on the 28th), for the advanced course on why mankind (or just men) continue to launch full-scale genocide upon their own brain cells and wallow in regurgitated body fluids, while throwing around the "F" word like they're in a high school locker room after football practice.

The question is: Do the Japanese effing well get the joke?
