Quote from Barney in How Your Mother Met Me
[flashback to March 2008:] Kelly: Okay, yes, you're doing something nice, but you're still bailing on me. The Mother: So I guess karmically, it evens out? Kelly: I'm just worried about you. The Mother: Don't be. Have fun. And who knows? Maybe you'll bump into someone tonight. [Kelly bumps into Barney] Barney: Oof. Girl, I will "shamrock" your world. [Kelly walks away] Barney: I'll- We'll- Okay.
