You know when you buy some popsicles you get these jokes written on the stick?
Pringles came out with “Pringles Prints”, where they put either Fun Facts or Jokes on the potato chip. I got the Fun Facts one.
One of the funniest, but TRUE!, facts I read:
Q: Do earthquakes only happen on Earth?
A: No. There are moonquakes.
I Have Cramps 
Now that’s definitely funny and true. It’s also something very few people think about. At least, I certainly don’t.
Out of curiosity, I drummed up this web link http://www.asi.org/adb/m/03/07/seismic-activity.html .
