Rock, paper...uh, I forget...

The other night (or early-early morning), I was looking up info on vasectomies for...a friend, of course. Imagine my surprise to learn the surgery may cause dementia!! Now my friend has an interesting dilemma: Another baby most certainly would drive her husband nuts, but the simplest solution (at least, for her) might also make him wacky.
(Or wackier...)
