Great line, KtB - "That's adorable!" would be another one.
I've used this before too!
I love this thread. I know / have known lots of kids who, upon mentioning the name of a band / film / director / whatever, will do nothing but quote related things (dialogue, album / film titles, whatever) to show you that they have THOROUGH knowledge of what you're talking about and that they approve of the fact that you like things that they like. That is the ENTIRE CONVERSATION. I met a kid at a party a while back who heard I liked indie music, and he cornered me and made me list bands and records that I liked so he could note how much he hated some of them (literally all he did was go "They're terrible" and then move on). After the party I found out that he really liked talking to me. Ugh.
One time I was in a "listversation" and I slipped this in.
Me: Do you like Ponys?
Kid: Oh yeah...they have a pretty cool sound.
Me: The animals?
This was before a band called Ponys came into existence. I think it's hilarious that people will lie about knowing bands / whatever just so they maintain their cultural wizardry stature. I'm guilty of having done this in the past (thankfully, I'm reformed), and I'd always ask myself why I felt the need to lie about something so stupid. It's ok not to know everything about everything!
