Not literally, of course, but when you're wrestling with 2 lil munchkins it's sort of hard not to let them win. Doing anything else tends to end up with someone bleeding or in pain. Ah, yes, the joys of fatherhood.
On the upside, I will never need one of those little Japanese women to walk on my back, as both of my sons are more than willing to walk - nay, jump repeatedly - on my back anytime.
