Everybody has dumb moments at times, but there are some people that are habitually stupid.  Most of us know a few habitually stupid people and they are the reason that everything comes with warning labels.  If you find humor in idiotic behavior then you need to get the book Idiots At Work so you can read dumb quotes from business people, stupid customer service calls, and outrageous warning labels. 

Here are some of my favorite warning labels......

1) "Don't use this for personal hygiene." On a can of Scrubbing Bubbles Bathroom Cleaner

2) "Warning: This Product Moves When Used. Exercise Caution When Riding." On a Razor Scooter

3) "Caution: Please do not use this directory while operating a moving vehicle.  On a telephone directory
