You know, I gotta shake my head and chuckle when junk like this happens. The simple, one man/one woman/marry/have kids/stay together forever has a world of difficulty all by itself. And for some reason, we think we have to add all the twists and turns of unmarried moms, divorce, test tube babies... My heart goes out to the poor folks involved in all that kind of stuff.
Let's face it, mankind is just really good at messing things up - and sometimes, we don't even need lawyers to do it!
Somehow I don't think these two dim bulbs would have had much success with the "simple, one man/one woman/marry/have kids/stay together forever" route either. Some people are just too dumb to make anything work out right.
