Father Abraham and McDonalds

Last week on Presidents Day, I was teaching the boys about President Lincoln and President Washington. They made little puppets with the two presidents on them. That evening during dinner I asked them to name their president that they had made. Ian said, "That's Father Abraham... Lincoln". Yes, he's been singing lot of Father Abraham at AWANAS! The boys also call the McDonalds restaurant "Old Macdonalds" or "Old Macdonalds had a farm". I'm waiting for the day that they ask me why it's called that since there's no farm there!
