Bottle Baby

S3, E9: Buddy's sister, Bunny, arrives for an unexpected visit and is invited to the Powell home for dinner. She asks Buddy to lie and tell their parents he asked her to visit since she used their mother's credit card for the plane ticket. Later that evening, she arrives at Sid's Pizza Parlor and sits on Charles' lap, then she kisses him. She leaves his table to sit with two college students and eventually leaves with them for a fraternity party. Charles becomes concerned and begs Buddy to find out what kind of trouble Bunny is in.
