Masochist

Last night Sam was laying on the kitchen floor playing with a train.  I heard all sorts of giggling and looked over.  He was laying there with his face on the floor saying, "Oh no!  Oh no!  Train's gonna get me!  CRAAAAAAAAAAAAAAAASH!"  And then he would run the train into his own nose and laugh and laugh.  I think there's somethin' wrong with this one.
