My wife said I wouldn't be able to cope if she left me and, to prove it, she moved out for a week.
She called after three days to see how I was getting on.
"I'm fine, thanks," I said smugly. "It's easy! I just bought a week's worth of Pot Noodles so I won't go hungry."
"I hope you burn your mouth on the boiling water!" she screamed down the phone.
