This is easily the best video you'll see all day.
To thank his fans for making "Riddick" #1 on the home video charts, Vin Diesel decided to post another awesome clip on his Facebook page.
This time, he's dancing and singing along to Katy Perry's "Dark Horse" and Beyonce's "Drunk In Love." Yep, he's doing the surfbort.
Our favorite moves happen around the 6:00 mark.
This isn't the first time Vin has posted a bizarre (but totally entertaining) video on Facebook. Last Valentine's Day, he serenaded his fans with a strange karaoke performance of Rihanna's "Stay."
Keep 'em coming, Vin. We love these!
