 He'd sing his song all day long, 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. Dancing and singing and giggling and wiggling, he got so silly, he could hardly let off.
