Quote from Barney in The Pre-Nup
Barney: Hang on a second. "A half million dollar fine "any time Mr. Stinson can't 'rise to the occasion,' cue sad slide whistle sounds"? Lily: [blows a slide whistle] Arthur: Hey, what's this about a shock collar? Robin: Ah, yes, we'll explain. Miss Garvey has many attractive friends who will come to visit. [fantasy scene:] Barney: May I offer you goat cheese puff pastries I made, mistress? Quinn: As long as you can do it quietly. [As Barney eyes up one of Quinn's friends, she presses a remote which sets off Barney's shock collar. He jerks around and falls to the ground] [present:] Barney: Wait, I'm confused. If it's not around my neck, then where's the shock collar? Oh, God. Men: Oh, God. Quinn: It's more of a shock ring, really.
