haha. i think you have your new avatar
seriously, consider the boob thing. if you don't tell anyone and make it so that it looks like something else (you do a little bit of photoshop'ing no?

) and then don't tell anyone until long after it's gone. so no one will never really know or see anything, but you did, technically, have your boob as your avatar.
i don't even want to take credit for this idea because i'm a philosophical emo loser. i don't have ideas like this. i haven't smoked weed today, i blame that. this is not me.
