Most highway billboards are a waste. The words are too small or too many. We never get most of them.

A clever billboard designer understands that he only gets a glance from folks driving by. So he better get to the point, and it better be visible and memorable.

Here are 5 Wyoming billboards that once seen can never be unseen, or forgotten.

1). How do you tell people they need to worry about an awkward health problem? Be direct.

2). Is it hard to explain how impressive something is? Use some imagination with a clever visual.

3). Adult humor is okay. As long as the kids don't understand why you are laughing.

4). Have an important message that no one wants to hear? Sneak it in.

5). Not sure what PETA was trying to say here but now I want a Chicken Sandwich.
