Watch this 2 minute, 33 second video right to the end for a cute surprise.
I didn't much care for the song, "Everything old is new again", but it truly has context when you see the ending.
Please do not spoil the ending in the combox.
EDIT: For those who don't know how to start it, just click the center once or twice and it will begin playing right in the blogpost. If you don't like the song, just turn it off and watch the slides - to the end!
EDIT 2: My understanding is that it originated with someone at this blog. Please clarify in the combox, and provide additional info for those interested.
