At the comic book store Sheldon wants to buy Leonard a nautical related gift and is choosing between an Aquaman character and a Batman squirt gun. Howard has been at his mother's house spending ointment on her back that has a high estrogen content and is worrying about his weight gain. At Penny's apartment she is having an argument with the pizza deliveryman about his tip while Leonard is showing her pictures from his trip. Sheldon comes by and wonders about all the takeout food cartons in her trash, while Penny acts funny since Leonard is hiding in the bathroom. Later with Amy, Sheldon wonders if Penny is cheating on Leonard. He jumps into her apartment and finds Leonard there and immediately becomes angry with him.
