Barney: Did you sleep with her sister?
Ted: No..
Barney: Did you sleep with her mom?
Ted: No..
Barney: I'm losing interest in your story

While this font is often mistaken for Helvetica, it's actually Helvetica Bold. I can actually hear the sound of her vagina being boarded up.

Ted: Barney, you've really grown up, you know that?
Barney: Thanks, now lets watch our two best friends have sex on tape!

Ted: Hi, I'm Ted.
Ashlee: Hi, I'm Ashlee -- with two E's.
Barney: Please, C's at most!

Barney: Alright, fine, the stripper at Stewart's Bachelor Party was a 15.
Ted: She was 15?!?!
Barney: A 15...like in blackjack.

Older Ted: I asked her about it years later, and, yes, that was the signal
