Did you know that Google gives you a happy birthday doodle? ...It's my birthday!
So, it's my birthday, and I went to Google to search something and the doodle was birthday cake spelling out Google. Mouse over says "Happy Birthday name goes here" I guess they have to have your birthday somehow (... maybe it was when I signed up for gmail to prove I was old enough or something).
It was kind of creepy at first, but kind of cool too.
