Most definitely.

To understand just how important the above sign is follow your fish to the Darwin Awards and learn about those who have done the human race a favor by removing themselves from the genepool. For example:

"3 February 1990, Washington
The following mind-boggling attempt at a crime spree appeared to be the robber's first, due to his lack of a previous record of violence, and his terminally stupid choices:

1. His target was H&J Leather & Firearms. A gun shop.
2. The shop was full of customers - firearms customers.
3. To enter the shop, the robber had to step around a marked police patrol car parked at the front door.
4. A uniformed officer was standing at the counter, having coffee before work.

Upon seeing the officer, the would-be robber announced a holdup, and fired a few wild shots. The officer and a clerk promptly returned fire, covered by several customers who also drew their guns, thereby removing the confused criminal from the gene pool.
No one else was hurt."
