Bob Dunn (March 5, 1908 – January 31, 1989) was an American cartoonist, entertainer and gagwriter who drew several comic strips.
In addition to his own strips, Dunn was known for his work on Jimmy Hatlo's Little Iodine and They'll Do It Every Time.
King Features syndicated Dunn's Just the Type from May 5, 1946 to November 24, 1963. It ran in the New York Journal-American and several other newspapers. Comics historian Allan Holtz commented:
Dunn began his career at King Features. He submitted gags to newspapers and magazines and sold skits to Earl Carroll for his Vanities on Broadway in 1930-31. In 1936, "he invented the knock-knock joke" (according to The World Encyclopedia of Cartoons) in a book he wrote that sold over two million copies. More successful books followed including I'm Gonna Be a Father, Hospital Happy, One Day in the Army and Magic for All.
