In yet another valiant effort to become the coolest dad ever, Dave Grohl recently joined forces with his daughter, Violet, to create a funky new shirt for the Nick Jr. show Yo Gabba Gabba! The new gear is part of a collaborative clothing line with Volcom and the popular kids' program. Biz Markie also designed his own top recently, but he didn't get assistance from his six-year-old.
Yo Gabba Gabba! also released a fun clip about their new line; it features Grohl, Devo's Mark Mothersbaugh, the Flaming Lips' Wayne Coyne, Jack Black, Jon Heder and more. Check out the full line at Volcom.
