If your heart races faster whenever you're near the object of your affections you can show the world exactly how much with an electric t-shirt. When you're apart your 'heart-rating' falls, but when you're together your garment literally lights up in glee. Those crazy Americans. There's a lot of crazy stuff on ThinkGeek, but really.. You can even buy a remote device to put near your PC, TV, Xbox or whatever it is that's nearest and dearest to you, so you can show how much you truly lurve your plastic pal. Remember.. the 14th's not so far off (so don't say we didn't remind you).
