Ted: [on the phone] Who the hell am I gonna bring to this wedding?
Barney: Ted, have you ignored all my teachings?
Ted: For the most part, yeah.
Barney: You don't bring a date to a wedding. That's like bringing a deer carcass on a hunting trip. Oh, Ted. Oh, Ted. No, no date.
Ted: Deer carcass, really? That's the metaphor you're going for?
Barney: Ted, it's a simile.
