This special Dad has been drawing on his kids sandwich bags for over 5 years. His kids don't see the images until they sit down for lunch and look to see what Dad drew for them on that particular day. I think it's one of the greatest things I've seen online for quite some time.
This is definitely what The Joys of Being a Parent is all about.
Plenty more pics after the jump...
There's more pics on David's Flickr Stream - check them out.
