J: 'Any idea how to use these things?'

Bumpity.

I'll bring the BEARDS.

My Google-Fu isn't all that strong, but here's what I found:

First, the URL of the search itself...
http://www.google.com/search?hl=en&source=hp&biw=&bih=&amp ;q=%22Men+in+Black%22+%22any+idea+how+to+use+these+things%22&btnG= Google+Search

...which only brought up one result; a review, it looks like.

I'm sure everybody is aware of this already....but anyway, the first time I saw the preview for Men In Black, which I believe was when I went to see Return of the Jedi Special Edition, I distinctly recall a bit of dialouge in the scene where the bug in the Edgar suit crash lands his ship and K and J are standing there ready with really sophisticated looking, powerful guns. The dialouge goes like "Do you have any idea how to use these things?" says J. "Not a clue." says K. For one thing, in the actual movie, K and J fire their guns BEFORE this line of dialouge would take place, but the line of dialouge never happens in the actual movie. Then...while I was recently watching a "behind the shades" in-look at the making of Men in Black on the sci-fi channel they showed that same missing scene, except this time it went "Do you have any idea how to use these things? No idea."

In the commentary i just watched with the director and tlj the director says he chickened out and put in a different line. Apparently a lot of the movie was changed as they realy didn't haveagood ending and changed some stuff.
