If you've got friends who eat your ice cream all the time, you've got two options. You can make new friends, which Ben & Jerry's can't help you with, or you can keep your ice cream away from thieving hands, which Ben & Jerry's can absolutely help with, thanks to its Euphori-Lock. Invented by a fan a while back, the Euphori-Lock is a combination lock that attaches to the lid of any Ben & Jerry's pint carton. Wait, are there people in this country who can't finish one of those off in one sitting? Man. What are their lives like, I wonder? More images after the jump. Via Laughing Squid.
