An elderly man in Perth calls his son in Sydney and says, 'I hate to ruin your Christmas, but I have to tell you that your mother and I are getting divorced; 35 years of misery is enough.'
'Dad, what are you talking about?' the son screams. 'We can't stand the sight of each other any longer,' the old man says. 'We're sick of each other, and I'm sick of talking about this, so you call your sister in England and tell her,' and he hangs up.
In a panic, the son calls his sister, who explodes on the phone. 'Like heck they're getting divorced,' she shouts, 'I'll take care of this.'
She calls her dad immediately, and screams at the old man, 'You are NOT getting divorced! Don't do a single thing until I get there. I'm calling my brother back, and we'll both be there on Friday. Until then, don't do a thing, DO YOU HEAR ME?' and hangs up.
The old man hangs up and turns to his wife.
'Okay,' he says, 'they're coming for Christmas and paying their own airfares.'
