While playing a game at the park:
G: ... So I'm going to do this, and then you're going to do that, capish?
Me: Capish? Who are you, the littlest mafioso?
While thinking up names for dogs:
Me: Okay, you win.
While G is showing me how she's styled the hair of her extra-large My Little Pony:
Me: That is one big pony.
G: Yeah, she could cause mayhem in Ponyville.
