All this talk of clipping and stuff made me have a thought. What if after humanity's extinct, a race of hyper intelligent aliens only found TF2 as the last remnants of our culture and took everything at face value?

"As you can see, the Class race was able to take any random object and adapt it for self defense, though sometimes their limited bone structure wouldn't allow them to firmly grasp the object in question so they would utilize their psychokinesis to levitate the object in or through their hands. This was perfectly natural to the Classes and caused them no physical pain what so ever."
