Fred Orsinger, self-proclaimed chairman of the Association for the Prevention of April Fool Jokes (A.F.P.O.A.F.J.), offered advice to help people avoid becoming the victims of April Fool jokes.

"The telephone joker is the most common," he warned. "I figure out he'll consume more than 8,000,000 man hours of work throughout the Nation today."

But he noted that should you see a pocket book lying on the street, it might be the setup for a standard gag, but it was nevertheless worth taking a look because "even if there is no money inside, you may get a good pocket book."

Orsinger's regular job was Director of the National Aquarium in Washington DC. [Oakland Tribune, Apr 1, 1940.]
