I'm not sure how this has come to be, but it seems lately I've been getting these preview clips while in a hotel with slow internet access.  Slower than home anyway.  But, clips are clips, and I do love getting them, so here are three for the upcoming episode "It's a Terrible Life".  It's a nice comedic rest after the two very intense episodes we just got (I'm not complaining though!).  Below is the official episode description:

Sam (Jared Padalecki) and Dean (Jensen Ackles) are living very different, normal and separate lives and although they are working at the same company and don’t know each other, they find themselves teaming up to solve a mystery with supernatural elements.  Guest stars Kurt Fuller as Mr. Adler. "It's A Terrible Life" was written by Sera Gamble and was directed by Jim Conway.
