Valentines Day is coming up! That means it's almost time to surprise your loved ones with something that won't get you dumped. Or if you're single to once again cry into a pillow and eat too much chocolate. It's also a time to be clever. If you're drawn to the funny side and would rather pull a prank on your loved one than get him/her the usual flowers or chocolates, you'll love this list of pranks pulled by couples. Assuming they have a sense of humor, this can be a great surprise. And even if they don't, it's funny for you and you shouldn't be with an unfunny person anyway. From replacing toothpaste with mayonnaise to replacing toilet paper with duck tape - the list is awesome! Take a look and get inspired by these couples.
