Okay, dumb title. But, again, I found this video on YouTube and just thought I'd like to share it. It's pretty clever, though you don't want them at your wedding, because I really think they'd steal the show.
Just FYI, I do have a page of wedding toppers you can buy (from various vendors) at my Squidoo page at http://www.squidoo.com/wedding_cake_toppers
None of them move around the cake like this couple, but, maybe that's a good thing. You wouldn't want your cake toppers making off with your wallet and car.
