I've just been watching some grey squirrels in our wood. Four of them were chasing from tree to tree uttering rather bad-tempered chirping noises all the while. Do squirrels play "he"?
Or perhaps spring is early and they are engaging in some courtship rituals. It's certainly very warm today: enough for lots of midges to be about.
Ah: a quick Google gives the answer: it's all about It rather than he!
Postscript: when I was a kid, we played "he" in the playground or on the streets. Then the game was called "it" - perhaps for PC reasons, and most US readers will probably know the game as "tag". Wikipedia lists lots more names too.
