This, of course, is the standard lame response all males revert to when cross-examined, so I thought I better expand my defence with a few solid facts. "For starters, I'm unlikely to be having an affair, because as you know, I drive a Skoda and as the newspaper stated when reviewing an overseas survey, 'Skodas are at the bottom of the list as chariots of choice for adulterers'.
"Now, if I was driving an Audi or BMW, it would be a different matter and I might have a case to answer," I suggested, standing in front of a wall light that hopefully bathed me in a halo effect.
"So, who's the young lady you've been huddling up to in 'Tosser's Palace'?"
"I think that's you," I responded, adding flatteringly, "since you've resumed exercising, it's taken years off you and onlookers probably think I'm dating a younger woman again."
"So, why would my friend tell me that her friend had overheard a public conversation, where you had supposedly stated, I've left my wife?"
"Well," I mused carefully, "if that conversation is even remotely true, it depends which wife I was referring to. You'll note your friend's friend didn't add 'current wife'.
"Of course, I cannot deny I've left a number of wives over the years," I concluded, adding forlornly, "anyhow, you of all people should know, I simply can't afford another divorce - unless I win Powerball for four weeks in a row."
