What should I drink when it´s boiling hot?

Not so curiously, everyone has an opinion on what to drink when it´s boiling hot. And, obviously, the healthiest option would be something  alcohol-free!  However, indisputably, that can not be  a serious suggestion, can it?

Anyway, after asking some mates to give me some advice the following is what they suggested.  You should drink:

  1. A Jamie Oliver Cosmopolitan
  2. A James Bond Vesper
  3. A white wine spritzer
  4. A fuzzy or pierced navel

Please remember that I´m utterly hopeless in the kitchen, so in your opinion which of the above do you think is by far the easiest to make?
