Cows

How many of you can tell the difference between a cow and a bull?  It was so funny yesterday, we went to buy milk at a farm, and Jacob could not figure out the difference between cows and bulls.  He calls the udders: milkers.  We (meaning Mommy, Sarah, Anna, and I) told him that bulls do not have udders. He responded with: "But Bull-girls have milkers!" :)  Jacob is so funny sometimes.
