Do you know any men who have had lots of children with lots of women?

I’ve been hearing about this show with a man on who isn’t married, and has lots of babies by lots of women. Some of these women have two or more children by him. It reminded me of a fellow I knew a very long time ago. I was in my late teens. He as in his mid twenties. We were friends. I never slept with him, but all other ladies under thirty had, I think. I believe he had nine or ten children by four different women. He told me he was having as many babies as he could, with any woman willing. He said he wanted lots of sons, so he wouldn’t have to worry about trouble when he got old, he’d have plenty of back up.
Does anyone here know someone like that?
What do you think of someone who does that?
