How Absurd Is A 40 Yard Dash Time?

let me tell you a story about the 40 yard dash. i knew this guy once who was definitly the fastest person that i had ever met before. he was very short but solid for a guy his size and fast as anything. well one day we decided to see just how fast he was compared to football players, so we grabbed his dad's yardstick, measured off 40 yards and then got a stopwatch. the first 3 runs were like 4.1, 4.1, 4.2. So I figured something was wrong. we re-measured, checked the stopwatch against a clock to make sure it worked, and sure enough everything looked fine. so we had him line up and run one more. his time was 3.95. anyway, this story is getting boring. long story short, his dad had cut the yard stick off at 30 inches and no one had noticed.
