“You don’t have to be crazy to work here, but it helps”

“You don’t have to be crazy to work here, but it helps” is a jocular sign that has been placed in many workplaces. “You don’t have to be crazy to work here…but it helps” has been cited in print since a least 1941, when it was said to be an old saying about Hollywood. In 1942, the saying was used in the petroleum industry. In 1943, the saying was applied to the federal government in Washington, DC.
 
“You don’t have to be crazy to work here—we can train you” has been cited in print since at least 1996.

“A commonly accepted saying in the burgeoning bureaus in Washington is, ‘You don’t have to be crazy to work here, but it helps.’ Many of the people can’t see any sense in what they’re trying to do, but they go on doing it just the same because there’s nobody in authority who can tell them to change.”
