Quote from Barney in Single Stamina
Barney: [to his baby nephew] Hey, buddy. Your parents are married. Now, listen, you. Just because you're being raised by married people doesn't mean you have to choose that lifestyle. High-five. Luckily, you got me. In 20 and a half years, you'll be 21, and I will be... Well, I haven't decided how old I'll be yet. But we are gonna bro out, uncle and nephew style. Stick with me, kid. I am gonna teach you how to live. Great suit, by the way. Who is the cutest?
