Consider this your weekend fix of reasons to love Nathan Fillion.

Laura Prepon was a guest star on his ABC tv show CASTLE, as the movie star Nikki Heat. When Prepon was a guest on Chelsea Lately last Thursday night she talked about how kissing costars ends up being very technical, but mints are par for the course. That is, unless you get distracted.

Apparently while on the set of CASTLE, Prepon discovered Peanut Butter Pretzels on the craft services table right before she was called to her kissing scene with Fillion.

As a joke, Fillion gave her “A Costco sized” barrel of PB Pretzels and said, ‘This is for your next costar who you have to kiss.”
