"The Sound of Angels Bowling." (http://sockkiah.livejournal.com/117759.html) They're... bowling. To celebrate Dean's birthday.

There's also Dean and flashback Cas and flashback Uriel.. in the form of seals. (http://sockkiah.livejournal.com/114306.html#cutid1)

“Seals are pure in spirit,” said Uriel. He had some issues with seal habits, but overall he approved of them much more than other earth species. Castiel felt freed by this.

The YouTube clips don't look too bad, yeah. Let's hope!
