Quote from Barney in Showdown
Ted: Why is this such a big deal?
Barney: Okay, guys, sit down, I've got to tell you something. [They were all sitting already] The reason I'm going on The Price Is Right is because I've decided that it's time for me to meet my real father.
Ted: Your father?
Barney: That's right. My father... is Bob Barker.
