Verbatim

Stealthy's Mum: "Have you seen this new show on Channel 4?"
Stealthy: "What show?"
Stealthy's Mum: "It's got this man in it who phones people [begins to crack up] and he's like, 'hi, I'm looking for Hummv', and the person on the other end is all 'HMV', and the man says 'Yes, Hummv!'"
Stealthy: "Mmm."
Stealthy's Mum: "It's so funny."
Stealthy's Sister: "That was new about two years ago, mum. You're so late."
Stealthy's Mum: "Well sorrreee! It's new to me!"
Stealthy: "Mmm."

I understand this now.
