April 13, 1940 –

The Looney Tunes short Slap Happy Pappy, directed by Bob Clampett, starring Porky Pig, debuted on this date.
Eddie Cackler is a parody of Eddie Cantor. The “boy wanted” sign and the five hatching eggs were references to all five of his children being girls, which was a running joke on his radio show. Then along comes a chicken resembling Bing Crosby, whose (then) four children were all boys. (Crosby later had a daughter and two more sons from his second marriage, long after this cartoon was made.)
