Well I thought this thread would be a good idea, and maybe help us all learn something from eachother.
Here's the idea: Post something that you know today, but didn't know yesterday. It can be as silly or as life-changing as you care to share with us.
Note that you don't always learn something new every day, but if you did today, I'd love to hear what it was! ^_^
I'll start: Thanks to a post from Loopy, I ended up finding out what a "budgerigar" was. Turns out, a budgerigar is a small parrot, and the only species in the Australian genus Melopsittacus. My first guess would have been some sort of pastry...
Live and learn, eh?
