Everyone loves Captain Mal from Firefly, Dr. Pomatter from Waitress, and now, Castle dude from Castle! Watch him in a funny series by Spike called "PG Porn." It's a dumb name, because it's really just a comedy sketch based off a porn plot. Watch it till the end or you'll miss the big gag (no pun intended) but Nathan Fillion is pretty hilarious as the construction worker who's there to "fix the cable." Sexy pin-up gal Aria Giovanni is in it too.
