You know, if you're out on a date, usually certain questions come up, like "do you have any kids?".
Should a guy that young say a number over two (and two baby momma's), I'd be out of there so fast you'd see flames and smoke in my wake.
You really got to wonder about people sometimes.
You seem to be assuming that the male date participant might accidentally lapse into truth. I kind of wonder. Look at superstars like Tiger Woods and Magic Johnson. I doubt very much they told their wives how they were spending their nights on the road.
At the other end of the income spectrum, about 35 years ago my late uncle was the manager of a small-ish satellite factory for a nationally-known hardware company. He told me once about a guy who surprised him by coming into his office one day and asking to be let off for the afternoon because his wife had just gone to the hospital to deliver a baby.
"But [Joe]," said my uncle, "didn't your wife just have a baby last month?"
[Cue stage whisper]"Don't tell nobody, Boss, but I got two wives."
Remember the saga of the thirty miners who were trapped underground for a month in Chile? They were from a small town, but one of them somehow managed to have two wives, neither of whom knew about the other until they both showed up to greet him when he stepped out of the rescue capsule. OOPS!
