Quote from Barney in The Stinsons
Barney: And then my mom got better. Which was miraculous. But it meant that I had to keep "Betty" around and cast a kid to play my son, Tyler. Lily: This is crazy. You actually cast your own son? Barney: Well, for a while, I got by borrowing/babysitting my neighbor's baby. And this one Christmas, when my mom was plowed on eggnog, I got away with a bag of flour and a Chuckie mask. But eventually, I had to hold auditions. [flashback to Barney in a room of aspiring child actors:] Barney: Four, eight, thirteen, you can stay. The rest of you may go. Stage Mom: You said that if I slept with you, my son would get the part. Barney: Well, apparently, I'm a better actor than your kid. Bring in the 11:00's! [present:] Barney: And that's how the role of Tyler eventually went to... Grant. Ted: Come on, Grant seems pretty good. Barney: You think so? Watch this. Hey, Tyler. [the kid is unresponsive] Tyler. Tyler. Grant. Grant: Yeah? Barney: See? It's like amateur hour over here. Call me crazy, but child actors were way better back in the '80s.
