Barney: Who mugged you? Was he wearing a black skull knit cap and a five o'clock shadow?
Marshall: Yes, Barney, because I got mugged in 1947 at the corner of Abbott and Costello.
Barney: A lie is just a great story that someone ruined with the truth.
Barney: I love to travel, myself.
Random Girl: Where's the best place you visited?
Barney: Hawaii's nice. A buddy of mine lives in Seattle, that's a good spot. But the best place, I have to say, the moon. Hi, Neil Armstrong.
