“Christmas in July” is the name of a movie in which a man called Jimmy is tricked into believing he's won $25,000 in a national radio contest. (It's from 1940, but the point remains.) He promptly goes out and blows his winnings on a shopping spree. When the truth comes out that Jimmy didn't win, the department store owner tries to repossess all the presents Jimmy bought for his girlfriend, his mother and everyone on the block.
