Robin: You know, um, there's something that I wanted to ask you, and I don't really know how to say it so... Here goes. Who's the crazy chick in the apron?
Woman: [baby talk] Someone naughty left his toys on the floor and needs to be spanked on his tushy-tush.
Barney: [baby talk] Uh-oh, I'm in "twubble."
Robin: You did it? How?
Barney: Last night, after admitting defeat, I just let myself go.
[flashback to Barney eating ice cream at MacLaren's:]
Woman: Ooh, that looks so good. Can I have some?
Barney: No! It's my ice cream! You can't have any!
Woman: Someone needs to teach you how to share. Who's your mommy?
[present:]
Barney: Challenge completed! Now, uh, can you get this freak out of here? I'm really scared.
