Jacket Off
Oh, and also, Misha was wearing a very spiffy jacket during his panel. At the end, when he dashed "backstage" (which was apparently nothing more than a curtain between the stage and the wall behind the stage) to put on the Wm. Shatner shirt, Dick made a joke he made many times during the con, but never more successfully than now, since Misha actually was wearing a jacket, and he actually might very well come back without it: "Maybe he'll leave the jacket on, or maybe he'll go jacket off." Which I always found to be the absolute height of brilliance and humor, because I am 11 years old still. You're killing me with this comic genius, guys! :-D As ever when it comes to SPN, dick (and Dick) jokes ftw!
(The "one layer of clothing" tag has never been so appropriate!)
