Quote from Barney in Bagpipes
Robin: Hmm. Hey, Barnstormer. Barney: Hey, Ro-Ro. Ted: Okay, now you have adorable nicknames? Seriously, what's going on with you two? Robin: Nothing. We're just happy. Barney: It's like Gandhi said, "Smile don't cost nothing, sugar." Ted: I'm not sure you know who Gandhi is.
