Before watching the video pasted after the break, it's important to consider an oft-overlooked fact of life. For each person of greater-than-average intelligence, there's one at the opposite end of the smart scale.
With that out of the way, we urge you to check out the video after the break. You'll be introduced to Robbie, a young man with a piece of black tape on his forehead. Robbie is about to demonstrate what happens when you stick your face in front of the tailpipe of what we believe is a full-size diesel-powered Dodge Ram pickup truck.
Why? Ostensibly it's to find out how much soot is expelled from said tailpipe. For the real reason why this exercise was carried out, please refer to the first paragraph of this post. See the rather predictable results in the video after the break.
Thanks for taking one for the team, Robbie.
