You always take decent drink to a party, none of this 4 cans of Tesco own brand and drinking the host's Stella or whatever, people who do that should be shot.
Wrong. You take the bottle of pink Cinzano that got left untouched at your gaff the last time. Then the host takes that to the next party he or she goes to. That same bottle of pinknCinzano has been doing the rounds since 1976. The Watneys Part Seven all got drunk though.
