“The brain starts working when you get up, and doesn’t stop until you get into the office”

A joke was told in Hardware Age in 1928 and was reprinted in many newspapers and magazines:
 
“The human brain is a wonderful organ. It starts working the moment we get up in the morning, and doesn’t stop until we get to the office.” 
 
The author of joke is unknown. American poet Robert Frost (1874-1963) has been credited since at least 1940, but Frost didn’t write for Hardware Age and the early citations of the joke do not credit him for it.
 
“The human brain is a wonderful thing. It starts working the moment you are born, and never stops until you stand up to speak in public” has been cited in print since 1949 and is a similar saying.
     
 
Wikipedia: Robert Frost
Robert Lee Frost (March 26, 1874 – January 29, 1963) was an American poet. His work was initially published in England before it was published in America. He is highly regarded for his realistic depictions of rural life and his command of American colloquial speech. His work frequently employed settings from rural life in New England in the early twentieth century, using them to examine complex social and philosophical themes. One of the most popular and critically respected American poets of the twentieth century, Frost was honored frequently during his lifetime, receiving four Pulitzer Prizes for Poetry. He became one of America’s rare “public literary figures, almost an artistic institution.” He was awarded the Congressional Gold Medal in 1960 for his poetical works.
