We're putting the "ass" in "fantastic" this week in viral videos, with a female sharpshooter who feels the recoil in her rump, a lobster girl who can't stay upright, the eternal struggle of junk in the trunk v. skinny jeans, and some Japanese aerobics fanatics with a bit of an over-sharing problem:

First we've got Lauren, a gun fanatic who most charitably agreed to be filmed shooting her Hungarian AMD 65 AK 47 .62 X 39 (full disclosure: we have no idea what that means) in spandex leggings:

Next we've got an anonymous hottie who shows off her rear view dancing on top of a bar before tumbling right off the side. For such a bottom-heavy girl, she tips over awful easy:

And last, but certainly not least, we've got the most outrageous English lesson/aerobics class you'll ever see. That's not what they meant when they said American guys are into ass, ladies.
