Oh, yes, English is a bastard language. Not because it's a bitch to learn, but because during the first millennia and somewhat after everybody and their brother invaded and took over some part of the British Isles for some time, leaving the remnants of their languages, along with a bunch of bastar... um, children born out of wedlock--probably didn't hurt the Brit's gene-pool when the Norsemen were... visiting, though I bet the Brit-women would have gladly had other circumstances, "oh christy, he's a posh squeeze, isn't he".
Back on subject, if you think you've got key's and keys' down, then you can jump the the possessive pronouns. His, hers, and its part with the apostrophe--just to f*ck with the Russians? Maybe to make room for the it's abbreviation?
