 Hey! Yo! This is my grandson. Today is his 18th birthday. When I was 18, ladies used to think I was fine. He's a smart guy, but I thought he could use a little advice today. Start putting away some money? Call your mother. You need to sign up with the Selective Service System. Save money, call mom, and register with SSS. Hey, Grandpa, this boy got that police head. The kind that roll up and stop wherever he wants to. Be the man. Register with the Selective Service System today at SSS.gov.
