Here's a 1960s commercial for HoJo Soda, which was created by Howard Johnson's, a large, now-defunct, American restaurant chain. 

Begins with teenagers having a dance party that gets interrupted by a middle-aged man wearing hip sunglasses and dancing. He asks for a soda and is told he is too old to drink HoJo. The boy in glasses behind the counter tells him Howard Johnson's made HoJo for people under 21!
