My husband thought the Pat Benetar song "Hell Is For Children" said "Be a good little boy and you'll get a new toy, now grab all your crap off the swing!" It really says "tell grandma you fell off the swing". I guess he thought the person in the song was really anal retentive about the cleanliness of the playground!
