[Quiet Man Cometh]

I've read a couple Hetalia comics, not my thing really, but the fan art on DA cracks me up. :D. One of my favourites has Francis (or is it Francois? France at any rate) with his wine glass and a big question mark above his head as he looks down at infant Matthew (Canada) being held by a very haggard Arthur (Britain) and a kiddy Albert (USA) tugging on his coat. Arthur scowls at Francis, shouting "YOU WISH!"

Apparently in the beginning of the manga Arthur and Albert were brothers, but when Matthew arrived Arthur took the dad role and USA and Canada are brothers now. At least, that's how it appears in fanfiction.
