[flashback to Ted telling Barney about Stacy:]
Ted: She plays bass in a reggae band.
[back to the flashback of Barney running into Stacy outside her yoga class:]
Barney: I'm gonna head out to a reggae concert. I'm a huge fan of reggae.
Stacy: Oh my gosh, I play in a reggae band.
Barney: No way, I wonder why Ted didn't tell me about that. Like I said, I'm a huge reggae fan. I should go inside.
[flashback of Ted on the phone with Stacy:]
Ted: [on the phone] After a while crocodile.
[back to Barney and Stacy outside the yoga class:]
Stacy & Barney: See you later alligator.
Barney: We are two peas. [Stacy laughs] Wow, take care. Namaste.
