Boys will be boys

[ShounenSuki]

I was wondering what the best translation of the sentence "Boys will be boys" was in Japanese.
I was thinking of something like 少年は少年です

Thanks in advance ^^

I am sure there is something equivilant in Japanese for such a common set phrase, but since I don't know of one perhaps something like やっぱり男の子ね。 captures the image of a boy running in with dirt on his face and a few earthworms in his pocket:

やっぱり男の子ね。
yappari otoko no ko ne.
As expected-boy-isn't it?
Ah! He's a boy isn't he? (or something)

男の子は結局男の子です。
boys are boys after all.
