Fat kids, skinny kids, Kids who climb on rocks; Tough kids, sissy kids; Even kids with Chicken Pox; Love hot dogs, Armour Hot Dogs; The dogs kids eat day or night. Bad kids. funny kids; Kids who fly a kite; Big kids, little kids; Kids who like to fight; Love hot dogs, Armour Hot Dogs; The dog kids love to bite. When man bites dog, that's news they say, But when kids bite dogs they yell 'Hooray!' For hot dogs, Armour Hot Dogs; The dog kids love to bite!"
