This 15-second clip is going viral for some reason. br br It’s entitled When Mama isn’t Home and shows a father and son making sweet music in the kitchen. br br Dad’s on the trombone and his kid is on the…oven door. br br The ditty kicks off with a short solo from trombone man before he’s joined by aggressive door slamming. br br The combination is beautiful. But it’s the kid’s head-banging which has really made this video an internet sensation.
