What did you learn today?

I'm basically a lurker of Reddit. I love TIL, askreddit, gaming, technology, science, and a lot more subreddits.

I love learning new things, and I try to do so every day, regardless of the importance of size of the discovery.

So, what did you learn today? What an ant eats? That your girlfriend isnt that funny at all? Perhaps, that you're exceptionally good at Battlefield 3, but only with one weapon.

Anything, small or big, feel free to share!
