12. Ben & Jerry’s Euphori-Lock

This was a terribly well-meaning invention. Trying to hide your ice cream from your family, friends, and roommates seems like a fools errand. It’s almost impossible to keep other people out of your delicious stash. So, Ben & Jerry tried to remedy this by creating a combination lock you could keep on your individual pint for safe keeping.

The other side of the lock has a little message saying, “I’m terribly sorry, but there is no ‘u’ in ‘my pint,'” which some may find cute, but may seem like a challenge to others. The greatest flaw in this design is that all it would take is a sharp enough knife to cut through the paper container.
