I have officially chosen the most impressive and entertaining Olympic sport, the one I could watch for several consecutive, catheterized hours: trampoline. I just can't fathom how any person could make his body do the things these trampolinists do, and as the boys and I watched I caught myself utterly awed, jaws agape.

When it was all over (and a gentleman named Dong Dong took the bronze), I had to blurt out loud, "How can a person do that?" And Robert piped right back with, "Dad, what are you asking me for? I'm only six years old. I don't know anything about how the world works."

When you write a blog that's mostly about parenting, you have to resist the temptation to prattle on about all the precious things your kid says. And that's a shame, I think, because one of the best things about parenting young children is watching them catch on to even the most subtle, peripheral things you didn't even know you were imparting. It's hard to talk about it, though, because it's too easy to make your conversational partner want to slam his head in the fridge.

If you feel the same way I do about this, now's your chance to indulge in a guilty pleasure. Let me know the funniest, most perspicacious thing your kid -- 0r your sister's kid, or your neighbor's kid, or your kid's kid -- said. It doesn't matter whether it was 20 seconds or 20 years ago, because this stuff is eternal. And to me, it's truly entertaining. Is there a greater pleasure than watching a brain being built?
