A note from the Offspring's official website states:

Hey Offspring Fans,

Watch the World Premiere of our new video, animated by Anthony Schepperd, for 'Dividing By Zero' and 'Slim Pickens Does The Right Thing And Rides The Bomb To Hell' right now!

So it's two songs from their 'Days Go By' album and an absolutely killer video, as you can see above.

The Offspring also just released a new EP called 'Summer Nationals' to coincide with their tour with Bad Religion, Pennywise and The Vandals. It's a whopping 5 minutes and 37 seconds long and features two Bad Religion covers and one of Pennywise.
