If you’ve seen the viral marketing campaign for Dexter last year, you’ll know this insert-a-name technology is nothing new. But this newest viral video is still pretty fun. 

Just type in your mom’s full name and e-mail address, and the site will send her a personalized video declaring her “2009 Mother of The Year.”

My only gripe: the site won’t let you embed videos, so I had to load a picture. See the video by clicking the pic, or send one to your own mom for Mothers’ Day.

For more interactive marketing goodness, check out Hotel 626 from Doritos (great if you’re a horror movie fan), Simpsonize Me, and Subservient Chicken.
