Jonathan Mann (who happens to write a song a day) came across this really interesting thread on Reddit one day calling for the most mind-blowing fact you've ever heard. Naturally, he wrote this delightful song featuring his favorite facts.

The facts (of which there are roughly 19) range from ridiculous things like "Each ejaculation has more sperm than there are people in the United States," to even more ridiculous things like "You see your nose at all times, your brain just chooses to ignore it."

Listen to the song for all the rest. If you need us we'll be here trying to see/not see our noses. (Via The Daily What)
