Ooops, I didn't read the entire thread and realize that Gregor already did the mandatory anal probe joke. My bad.
But while we're on the topic, does it make sense to anyone that a civilization advanced enough to travel light years through the galaxy just to meet us earthlings would be content when they get here, with abducting Bubba from his trailer and conducting an anal probe, tucking him back in and then going home?
I mean, think it through. I've studied the digestive process in biology class, and it's really not that complicated. A few polymers, enzymes, monomers. Not much else up there except some cellulose and undigested corn husks. Really, do you people realize how long it takes to travel across a galaxy? Just to look at poop? I'm just sayin' is all....
