Picture this: you are on the beach and notice someone in trouble. Dressed in your Baywatch costume, you run dramatically towards the person in danger and it's as if you are moving in slow motion. You're almost there. Hopefully you won't be too late.
You arrive at the person with a distressed look on their face, staring into their empty cooler. “There was lots of cans in here when I got here, but now they're all gone!” he/she says. “What am I going to do?” Que heroic music as you say, “Not to worry, I always carry extra.” Everyone cheers as you reveal the safety float you were carrying was actually a beverage dispenser. David Hasselhoff himself would be impressed.
