Kate gets invited to her hot neighbor's Halloween party, so BJ tries to help Kate break free and be someone completely out-of-character for the night. Meanwhile, Ben and Tommy decide to stay home and hand out candy to the trick-or-treaters in hopes that they'll meet some hot moms, but the night takes a turn when Tommy unknowingly eats some of BJ's "candy" from Amsterdam, and Kate bonds with Will (guest star Stults), a single father.
