April Fool Fun Rationed (1943)
The Associated Press reported that the Society for the Preservation of Practical Jokers had issued an advisory to its members warning them that "in view of the war's restrictions on what some fools consider fun" practical jokers should proceed with caution "otherwise, there might be casualties."
For instance, it would be considered sabotage to put a brick under an old hat on the sidewalk for passing pedestrians to kick, because shoes were now rationed. It would be similarly unwise to put salt in the sugar bowl, since one cup of coffee ruined is considered "grounds for justifiable homicide." The end of the article revealed, "April Fool! There's no such thing as a Society for the Preservation of Practical Jokers."
