:hallow3: <-- yeah, I know it's not really a birthday thing, but I hadn't seen it before, it looks cute, and so... well... ah... I think the little ghosty is wishing you a happy birthday as well. It's saying, "yippee!!" in your honor.
Be sure to watch the Today Show. I tipped them off that it was your 100th Birthday. I didn't have your picture though so I just used a pic of the Tanning Mom!
