Interesting fact about Play Hooky
The origin of the term "hooky" is in the 14th century Dutch game 'hoekje', or as it's known in American culture – 'hide and go seek'. However, the first recorded use of the phrase "playing hooky" was in 1842 in the Brooklyn Daily Eagle: "When I was a child, I thought as a child.... hunted birds' nests, played hooky, and chased butterflies... ". The analogy behind the story is playing games while skipping school.
