That kid is an alien, the goofy look is cuz he's about to meepmeep across the desert at the end of the movie. But what movie? its been awhile...Maaan is been awhile. Did it star Christian Slater? Was he a seti scientist? Was it a climate message movie? I need a minute...
EDIT: Haha as other poster said, it stars Charlie Sheen who for some reason i always get mixed up with Slater. So close... (not close)
Oh wow, I also have that condition on my legs. It makes your knees bend a little more than usual. I also can bend my fingers more than what most people can. I'm not sure if it's a good thing though.
