[flashback to 23-year-old Barney talking to his brother James, who is wearing a beer helmet and a football shirt:]
Barney: But I don't know the first thing about seducing a woman. What do you...? How do you...? Where do you...?
James: Stop. Don't overthink it. You don't want to get the yips.
Barney: The yips?
James: Yeah, when you overthink simple things so much that you can't do them at all.
Barney: The yips.
James: Yeah, it happens to athletes all the time. Like the second baseman who suddenly can't throw to first or the figure skater who does a perfect triple toe loop and then loses it on the arabesque. [laughs] I've actually really been getting into figure skating lately.
