We've all heard from some supposed alien abductees that they were subject to anal probes during the time in alien custody. They never seem to be able to explain the reason why aliens would be so interested in our asses that they would come from God knows where just to stick it where the sun don't shine. But maybe there's a good reason for them to be interested in crap we don't give a shit about, or do we? Recently scientists have "discovered" how important our intestinal flora is to our overall physical and mental health. So perhaps that's what's behind their interest in our poop. They understand that to survive and live on Planet Earth they need to be able to feed their bodies just like us. Without having evolved on this planet, alien beings would be unable to digest the same food we do. But if they have our bacteria and enzymes they could breakdown and absorb our food. So there's a good reason for anal probes. Humans do it now too to introduce healthier organisms to their own biome. Now aliens can live and thrive among us! Isn't that nice to know! You can relax your spincter now....
So now that anal probes have been explained, it seems more likely that those may have been real encounters. Aliens can only pack so much Tang in their spaceships on the way to earth. At some point they need to refresh their larders, whether they decide to hang out here for awhile or continue on to more desirable destinations than this fucked up planet.
Maybe they think we're like dogs and can only have our temperature taken that way? No, I'm not relaxing my sphincter.
I was just imagining the intestinal issues the aliens experienced that made them resort to anal probes and then using the shit one way or another.... UFOs = Unidentified Farting Objects. I can imagine the same thing would happen to human space travelers attempting to eat alien flora or fauna.
