Sheldon is forced to take care of Amy when she gets sick, thanks to a special clause he built into their Relationship Agreement. He begrudgingly takes care of Amy, who loves the extra attention so much that she continues to pretend to be sick even after she's gotten healthy. When Sheldon finally discovers that she's healthy, he tells her that his father would've spanked him for the ruse she pulled - an idea that excites Amy greatly. Meanwhile, Howard is forced to go over to his in-laws for dinner, where Bernadette volunteers him to go on a fishing trip with her macho father. Howard has no clue how to fish, so he enlists Penny to give him a tutorial about being 'manly.' Howard eventually stands up to Bernadette's father and tells him he doesn't want to go fishing, and the two of them decide to go to a casino instead.
