'Terry said I was hairy arse today, Mum.'
'That's good.'
'Why?'
'He couldn't have seen your bum!'
'No. He hasn't.'
'It's hilarious, Penny, not hairy arse. You wouldn't call an expert a geni arse would yo?'
'You mean genius.'
'Of course. Anyway why did Terry think you were hilarious?'
'I told him some jokes.'
'My my. Have we got a comedienne in the family?'
'Could be. I get my jokes from the internet, though.'
'You can learn about almost anything there, I hear.'
'Seb says he has picked up quite a lot of useful information.'
'I expect he has. So what was your funny joke?'
'It was a knock knock joke. They are the best ones. I have given j.w. five marks for all his knock knock jokes.'
'I see. So this j.w. writes jokes for the internet?'
'Yes and other things as well but they are boring. I only look at the jokes.'
'So what was the funny joke?'
'This one is mine, actually. Knock knock. You have to say who's there?'
'OK - who's there?'
'Penny.'
'Penny who?'
'Penny for your thoughts!'
'I don't think that's too brilliant.'
'The one I like is Knock knock, Who's there - Ian.'
'Ian who'
'Ian and out'
'Yes, that's a bit better.'
'I suppose you know about Lydia.'
'Sure - lid of yer dustbin. How did you know that?'
'I've been at school as well.'
