When directors like George Méliès and D.W. Griffith were pioneering filmmaking at the beginning of the 20th century, neither had any intention of grossing out audiences with the use of bodily fluids on the big screen. But as cinema has evolved from a technical standpoint over the years, some of its subject matter has reverted back to the grade-school humor that we all grew up with. For better or worse, this kind of stuff sells, and the movie industry has been rolling in billions ever since.

In recent decades we’ve seen more urine, vomit, and diarrhea on the screen than ever before. For some, this is absolutely nauseating, but for others it speaks to the 10-year-old in all of us that just can’t get enough of it. And in this Friday's new movie, The Paperboy, there is a scene that has already gained notoriety around the web for featuring the usually-reserved Nicole Kidman squatting down over teen idol Zac Efron and unleashing a hefty stream of urine on his face and chest after he is stung by a jellyfish. 

This kind of grotesque act is nothing new, and to get you in the spirit for this latest example of crass humor, Complex looks back at The Most Disgusting Uses of Bodily Fluids in Movies
