What's a Rutabaga?!

Jen has been posting how big her little gummy bear is, which has been fun to watch, and I started reading about the wk. 25 developments of our little guy, and it said my baby is the size of a rutabaga. Um... I know I'm not super handy in the kitchen, but I seriously had no idea what a rutabaga was. Luckily, it had a link! And this picture! So I had to figure out what exactly a rutabaga is. And the results were... ewww. Not appetizing.
