Quote from Robin in The Final Page (Part 1)
Robin: Yeah, I'm with Ted. There is no one I hate enough to throw into a pit. What? Future Ted: [v.o.] When Robin's most hated coworker Patrice started dating Barney, she became obsessed. Lily: Patrice, Patrice goes in your pit. Robin: Guys, I told you, I am done obsessing about Patrice. Just drop her. Lily: Drop her in a pit. Robin: Enough.
