Nephew amusement

Nephew: "You're my favourite person."
Me: ".. Is this the part where I say 'thank you', or the part where I ask 'what did you do and should I bring bail money'?"
Nephew: "You can say 'thank you'. I just wanted to tell you, because I love you. You're my favourite aunt. The other one, I don't like.I like that I can call you up and talk to you, and you talk to me like I'm one of your friends and not like you have to talk to me because we're related. And you don't treat me like I'm retarded just because you're older than I am. If we were characters in South Park, you'd totally be my Stan."
Me: ".. Thanks!"
Nephew: "And Other!Aunt would be something really gross!"
Me: "Like poo?"
Nephew: "Grosser."
Me: "Vomit?"
Nephew: "Vomit's not grosser than poo!"
Me: "Speak for yourself. I can't taste poo."
Nephew: ".. Ok, you have a point, but it's a lateral move on the gross ladder."
Me: "Ok. How about the spooge that Paris Hilton coughed up in the Spoiled Whores episode?"
Nephew: "YEAH! Regurgitated whore spooge! Yup, that'd be her."
Brother, in the background: "What the hell are you talking about?!"
Nephew: "What character Other!Aunt would be, if she was a character on South Park."
Brother: ".. you're talking to [spookyevilone], aren't you? I hope?"
Nephew: "Yes!"
Brother: "Then all I have to say is.. " *pause* "Don't let your mother hear you talking like that. Ever."
