Someone put together a hilarious collection of safety graphics that are real graphics from the US Homeland security website, but then added their own interpretations. Here are a few examples:
If you spot terrorism, blow your anti-terrorism whistle. If you are Vin Diesel, yell really loud.
If you've become a radiation mutant with a deformed hand, remember to close the window. No one wants to see that.
I can't stop laughing at these! Enjoy.
