<P> 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!" </P> <P> A merchandising campaign accompanied the adverts and the Humphrey - themed mugs, milk bottles and straws are now collectors items . The campaign was devised by John Webster of the Boase Massimi Pollitt advertising agency . </P>
