Quote from Barney in Robin 101
Future Ted: [v.o.] Kids, your uncle Barney had been called a lot of names over the years. [flashback montage:] Woman #1: [throws drink in Barney's face] Jerk! Woman #2: [throws drink in Barney's face] Bastard! Woman #3: Barack Obama Jr.? Barney: Mm-hmm. And yes... we can. Future Ted: [v.o.] But there's one name none of us ever expected to hear him called. Robin: Boyfriend. Barney Stinson is my boyfriend. I've said it, like, a hundred times it still sounds weird to say.
