My dad used to tell a story of the only time he was ever struck by his mom was for singing There's a german in the grass / With a bullet up his ass / Pull it out, pull it out / Boy scout! Never heard anyone else knew this one. It would have happened in the late 20s or early 30's. As a child I used to sing something that went Underwear, Underwear! How I itch in my new Underwear! My older sisters taught me that one in the early 60's. Could date from the late 50's.
