Rain-man

I've decided that Ethan either has more indian blood in him than I realized, or he was a rain-man in a past-life. He has been sitting around lately (probably over the last two weeks or so) chanting random gibberish to the same tune over and over and over and over. It gets to where we finally have to tell him to stop...then about five minutes later he absentmindedly starts up again...then is reminded again and stops for good....for at least 1/3 to 1/2 a day....and then it starts again. LOL....how weird is that?!?!
