Gee, I finally got my brand new computer today, and I can't think of a better very first message to send out than

Takes me back to the good old days
Happy birthday to you!
You sure grew out of your baby ways
Happy birthday to you! You say it's your birthday, we wish you many more
With health and wealth and friends by the score
Cut the (virtual) cake and let's eat some more
Happy birthday to you!
