A #dadjoke is a short joke, 

typically a pun, presented as a one-liner or a question and answer, but not a narrative.[1] Generally inoffensive, dad jokes are stereotypically told by fathers among family, either with sincere humorous intent, or to intentionally provoke a negative reaction to its overly-simplistic humor.

 Many #dadjokes may be considered anti-jokes, deriving humor from an intentionally unfunny punchline.[2] An example dad jokes goes as follows: A child will say to the father, "I'm hungry," to which the father will reply, "Hi, Hungry, I'm Dad." While the exact origin of the term dad joke is unknown, a writer for the Gettysburg Times wrote an impassioned defense of the genre in June 1987 under the headline "Don't ban the 'Dad' jokes; preserve and revere them".[3] The term "dad jokes" received mentions in the American sitcom How I Met Your Mother in 2008[4] and the Australian quiz show Spicks and Specks in 2009.[5] In September 2019, Merriam-Webster added dad joke to the dictionary.[6]
