*Banging your head against a wallburns 150 calories an hour.

My question is, how exactly did they measure this to find it out

*Pteronophobia is the fear of being tickled by feathers!

I've also heard that some people can actually tickle themselves, but it's a personal disorder. Reason being your brain knows what you're about to do as you do it. I accidentally tickled myself and jumped because I had no idea I had done it. XD I practically fell out the chair

*A flock of crows is known as a murder.

Hmm, this is good information to know. That means there's a murder outside of my window XD
