Castle took a trip to the humorous side on "The Fast and The Furriest," airing an episode that centered on the possibility that Big Foot is out there somewhere.

Next Monday, however, the ABC hit turns deadly serious, as Kate Beckett pulls a Meredith Grey and gets herself involved in a literally explosive situation: the detective steps on a bomb and must stand completely still while law enforcement does its thing.

And while Rick tries to keep her spirits up by debating aspects of their relationship.

We somehow doubt Beckett will get blown up, but watch the official network teaser for "Still" now:

NOTE: This episode will now air on April 29. ABC made the change out of respect to the Boston Marathon bombing.
