My friend was attempting to vacuum some dead ants from around the front door of his house. They just wouldn't suck up the hose. He suspected a clog and took a look down the hose. Couldn't see anything wrong. So, he puts one end up to his mouth, and blows. Problem was, he had the other end turned toward his face. All the stuff clogging the hose comes out in a big puff, leaving him covered in dust and yuck.
Ever done a toatally stupid thing that you could have avoided if you had just thought about your actions for one more moment? I know I have.
