Great source, thanks PacoFor fun I asked Bing to show me some "crazy facts. Here is it's answer.
Here are some crazy facts that might surprise you:
I hope you found these facts interesting!

- Your brain uses up around 20 percent of your body’s blood and oxygen1.
- There’s a company that turns dead bodies into an ocean reef2.
- The name “bonobo” resulted from a misspelling2.

- You can buy a flying bicycle2.
- Dolphins sleep with one eye open2.

Yes, but couldn't that fact account for the expression?... that the expression implies the apparent custom of some of the slobbier members of our human species?If someone tells you they're "sweating like a pig" you might want to point out to them (if you're that sort of person) that if they were being biologically accurate, that would mean they were not sweating at all. Swine are born without sweat glands, so when they need to cool off, their only option tends to be to find a cool puddle of mud they can roll around in.
