Quick thinking

My youngest lad came in and asked me if his friend could visit and stay over, sometime this week.
Well, I didn't fancy it because, well, it's Christmas and I have enough bother without looking at another little tit running round, screeching like a cat, that's had its nuts caught in a grinder....so, thinking on my feet, I said;

'I don't think your mum likes him, so better leave it til some other time, when she's working.'

Feeling quite proud of myself, for the quick thinking like, I went back to the TV.
Meanwhile, the little traitor, ran out to his mother and said;

'Mum, dad says that you don't like Dick, and he can only come, when you're at work!'

Jeeeeez....she's hidden the TV remote; Why couldn't his parents have Christened him 'Andrew' or ....something?
