On a little boys first day of kindergarden his grandpa was driving him to school. They passed a field of cows and the little boy said, "Look grandpa, moo moos." His grandpa said, "You're going to kindergarden now, you have to talk like a big boy. Those are cows." "Okay grandpa, cows."
A few minutes later they drove past a train and the little boy said, "Look grandpa choo choo." And the grandpa said, "What did I tell you. You have to talk like a big boy now. That's a train." "Okay grandpa, train."
