Marlboro is giving away free leather keychains to Hiffers outside of MA or MI. Simply enter the Marlboro Sweepstakes by clicking on which prize you want to win, then you should be offered the free keychain.
This will never go on my keychain though. It will 100% confuse Drunk Goob. After growing accustomed to feeling leather along with my keys, I'll inevitable stumble home one night and spend an hour trying to unlock my door with my wallet.
