Real caption: Time. Minimizing time spent exposed will also reduce your risk.
Parody caption: Try to absorb as much of the radiation as possible with your groin region. The current world record is 5 minutes, 12 seconds.

Real caption: Local authorities may not be able to immediately provide information on what is happening and what you should do. However, you should watch TV, listen to the radio, or check the Internet often for official news and information as it becomes available.
Parody caption: When the looting begins remember to consider the weight/value ratio. Here we have a few examples of high value, low effort.
Hilarious. Check out the others here, without the original captions. Give me other captions for these if you can think of any haha.
