Dumb Warnings 
In the style of Dumb Laws, here are dumb warnings. I particularly enjoyed their top ten dumbest warnings and I think you will too. A nice section is the random warning which is a good way to experience the humor of these warnings. Want to just go through them however you want? Go through their warning index and pick and choose as you please.
Have you read a dumb warning on something you’ve bought or operated? If so you can submit a dumb warning.
You can even check out the Dumb Network which has things like Real Haunted House and many more.
