Yeah, it has happened to me too!
I have a better one though...I worked at a bar for a while, they had a TV on the far wall. I couldn't see it very well, it seemed blurry to me. So I went to the eye doctor, he told me my vision was 20/25. Never having vision problems before, I figured I better get glasses because I couldn't see a TV that was 15 feet away. I went to work, put on my new glasses, and the TV was STILL blurry. One of the old timers at the bar said, "Oh, THAT TV has been blurry for the past FIVE YEARS, the picture is NEVER clear!"

What an idiot...
