"One of my younger brothers had a tattoo done on his leg of my niece's art and I loved the idea, so I ran with it to do my whole right sleeve," Keith told ABC News. Keith started the tradition back in 2008.
Keith has even allowed Kai to tattoo him himself. He told ABC News, "It is a great bonding experience for us -- from choosing which piece we will tattoo to discussing the previous ones, his experience of drawing it, and even the connection of him being able to help with tattooing some small sections of the last three tattoos we have done. "He's a pretty rad kid and it's a magical experience to share with him." I told you he was a cool dad.
