Man: Oh no!
Woman: What is it?
Man: 'Josh and Henrietta would like to have the pleasure of your company at a drinks party, next Saturday evening ...'
Woman: Oh no, Josh and Henrietta ... they’re not that couple who ...?
Man: Yeah exactly! And it gets worse ...
Man: 'Formal dress ...'
Woman: Argh ... it means you’ve got to wear a suit ...
Man: At the bottom it says 'RSVP'. What does it mean?
Woman: You’ve got to reply.
Man: But I don’t want to go, so what can I say?
Woman: Tell them you’ve got a dentist’s appointment.
Man: Josh is my dentist!
Woman: Tell them it’s your grandmother’s 100th birthday party.
Man: But they know my granny died ages ago.
Woman: Tell them your dog’s sick and you’ve got to take him to see the vet.
Man: It’s no use – I’m just going to have to tell them the truth ...
Woman: The truth? 'I’m not coming to your birthday party because I think you’re boring and stupid?'
Man: Maybe not then ...
Woman: Tell them this: 'I’m unable to attend because I have a prior engagement.'
Man: 'Prior engagement'?! And … they won’t be offended?
Woman: Absolutely not.
