The British milk company Unigate produced a series of TV advertisements in the 1970s featuring characters called the Humphreys. The Humphreys were milk thieves whose only visible presence was a red and white striped straw with which to suck up the milk. TV personalities of the time, including Barbara Windsor, Arthur Mullard and Rod Hull featured in the adverts, but the campaign is best known for the slogan: "Watch out, watch out – there's a Humphrey about!"
