Quote from Barney in The Playbook
Barney: It's all in here. Everything from basic moves like "the don't drink that." [flashback to Barney at MacLaren's rushing over to a woman at the bar:] Barney: Whoa, don't drink that. I saw some guy slip something in there. Woman: What? Who? Barney: Uh, that guy. [points to Ted, at the other end of the bar, who is then tackled by the barman] Woman: Thank you. [Barney winks to camera]
