Ted: Okay, this may come as a shock to you, Barney, but people don't like to be lied to.
Barney: Wrong. They don't like finding out they've been lied to. "Because a lie is just a great story that someone ruined with the truth." Barney Stinson.

Future Ted: [v.o.] Kids, you may be wondering how many of these stories I'm telling you are true. It's a fair question. After all, there's a fine line between a good story and a bald-faced lie. I've never met anyone who could work that line better than your Uncle Barney. Heck, he could jump rope with it.
[at MacLaren's:]
Barney: I love to travel myself.
Sarah: Really? Where's the best place you've visited?
Barney: Hawaii's nice. A buddy of mine lives in Seattle, that's a good spot. But the best place, I'd have to say the moon. Hi, Neil Armstrong.
[later, in the apartment:]
Ted: No! You did not convince a girl you were the first man to walk on the moon! That happened seven years before you were born.
Barney: Ted, baby doll, minor hurdle.
[flashback:]
Barney: Oh, yeah, well, our spaceship passed through a wormhole or some gamma rays or something. I started aging backwards, blah, blah, blah. So, you work in a yogurt shop, that must be wild.

Marshall: Although, I did actually work in a yogurt store in high school. And it was indeed wild.
Barney: Anywho, 20 minutes later, the eagle landed. We knocked space boots. Houston, we have a moaner. Other space related double entendres.
