One half of a phone conversation between pink_weasel and her mother with interruptions from myself:-

PW: We’re going up to town later to buy Steve a wedding shirt.
…
PW: Yes, and cuff holes!
VTT: Cuff links.
PW: Cuff links.
…
PW: So what do you call the other bit? The holes?
VTT: The holes come free with the shirt.
PW: Apparantly, the holes come free with the shirt.
[Laughter at both ends of the phone line]

And I know this will keep them both amused all day long.
