Not only is it embarrassing to hang out with your parents at the age of 18, it's even worse to hang with your grandparents. How embarrassing is it when your grandparents produce a song for your birthday and the video goes viral on YouTube? The video title is'18-year-old birthday blues for Josh on his 18th birthday'.

You guessed, it grandpa is a lousy piano player! But it's fun to listen to. Take the jump and give it an ear.
