You're at the beach and its one of those rare perfect days. You peer through your shades and see not a single cloud in the sky. Being the responsible adult that you are you make the decision to lather up with the necessary SPF, when suddenly you're stricken by a terrible thirst. Hands greasy you try to open a can of Light Hearted Ale, and your fingers can't gain purchase on the pull tab. Panic sets in but you remember at the last moment that your trusty key-chain also doubles as a can opener. Thirst slaked you go back to the perfect day.
