Lorelai: How have you been spending your time lately? Anything new and fancy?
Richard: Not really. I joined a barbershop quartet.
Lorelai: Aha.
Richard: What do you mean, "aha"?
Lorelai: And what does the barbershop quartet entail?
Richard: It's a musical group. We dress up in outfits.
Lorelai: Aha.
Richard: Stop saying that.
Lorelai: What kind of outfits?
Richard: Well, old-timey period things.
Lorelai: Straw hats, vests?
Richard: That kind of thing. And don't say "aha" again. It's loud.
