You can make jokes. I can take it and I usually deserve any crap that I get.
Or you can do what I did -- skip the kids and go right to grandkids. Marry somebody who already has grown kids with kids of their own. Grandkids are great and when they're not, you can ship them back to their rightful owners!
And depending on how much you like the parents of said kids you can corrupt them - make sure they go home with some "extra" stuff they learned from grandpa!
