Quote from Barney in Mom and Dad
Barney: Oh. Whoa. Look. My dad hasn't seen my mom in years, not since he bailed on her. Robin: Oh, man, take it from a fellow child of divorce, this could get real messy. Jerry: Loretta, good to see you. Loretta: You, too, Jerry. [They politely shake hands and give each other a small kiss on the cheek] Barney: Wow. Robin: Yeah. Thank God, no drama. Barney: They're in love! My mom and dad are getting back together again! Robin: Uh-oh.
