Check out these food related t-shirts from threadless.com. These were some of my favorites.
I don't remember what this one is called, and it's from a while back, but I couldn't find it anywhere on their website. That makes me sad, because I really loved this one enough to buy it.
They sell these in little kids sizes too and onesies. I thought the "cookie loves milk" would be so cute as a onesie on our little guy.
