It's the question on everybody's mind: how many different types of guns were used in the 2007 Dan Fogler comedy Balls of Fury? It's a question that has baffled fans, movie historians, and expert scientists for quite some time now. Finally, there's a website brilliant enough to solve the mystery.

Enter the Internet Movie Firearms Database (IMFDB). It's like the IMDB, only instead of generally useful info on movie casts, release dates and box office info, you have page after page of cataloguing every gun in every scene of every movie and television show (including many screenshots). This level of dedication is truly astounding and praiseworthy, unless the editors of the IMFDB are crazy gun-nuts. In that case, a film database website can be admissible as evidence in court, right?

Oh, and to answer that important question: there are 19 different types of guns in Balls of Fury, including an M4A1 Carbine! Now you know, and knowing is half the... something. I don't know. (Boing Boing)
