 He'd dance and sing and laugh and smile and after a while he'd roll right on the ground. He'd sing his song all day long, he had no words, just this crazy sound. Called the laughing song, all day long. Called the laughing song, all day long. Called the laughing song all day long, the laughing song. He'd laugh, he'd laugh, he'd laugh, ha ha ha, he'd laugh. There were days when this boy was so wound up he practically laughed his head off.
