Multiple Personality Day – March 5
January 5th is National Whipped Cream Day in the United States. National Whipped Cream Day falls on the birthday of Aaron Lapin, the inventor of whipped cream in an aerosol can (Reddi-Wip). The first whipped cream in cans was sold in 1948 in St. Louis by milkmen and since then gained special popularity among housewives.
So, Reddi-Whip and I were both born in St. Louis in 1948, but on different days.
