#21 sounds fishy. Hair only grows about 15-16cm's a year. Perhaps they mean if you laid all your hairs end to end?

#10 my dog sleep on his back, I know this because he snores.

#19 Hmm... we need more facts about toes

"facts"
like your bones are stronger than steel? doubtful

Once again I remind you that humor sites are not the best sources for finding truthful facts. Probably the same types who need reminding not to cite Wikipedia and that Snopes is not a trustworthy site either.

@Christmas I use Wikipedia constantly, and I've never found it to be seriously incorrect about anything I've worked on. I know this because I double and triple check everything I use it for.
