I need help getting GTA 4!

Omg, i know its been like 2 montyhs since its came out, but my parents will never give in to letting me get it, nor renting it. I need a plan or something to get it, or someway to persuade them, idk where the bad sexual stuff is, but I just want it to blow stuff up, so give me a little help on where the bad things are and everything, thx ;)

if your over fifteen and allowed to watch R then tell em its like a movie its not real and also ask nice and do chores. there is a strip club, hookers every were so...:)
