Eleven volumes of Chickenman can be purchased on iTunes; but one volume will probably do you just fine. To start.
Chickenman is an American radio series that spoofs comic book heroes. It was created in the mid 1960s by Dick Orkin, who at the time was a production director at WCFL in Chicago, Illinois. Its famous catch-phrase is, "He's everywhere! He's everywhere!"
The series was loosely patterned after the Batman television show. It made its appearance in the spring of 1966 as a segment on radio station WCFL's Jim Runyon Show. Runyon served as its narrator. Orkin voiced the hero throughout the 195 episodes.
In the series, the super hero known as Chickenman is Benton Harbor, a shoe salesman at a large Midland City department store. Because of his Monday to Friday working hours, Chickenman can only fight crime on weekends. The main characters include Police Commissioner Benjamin Norton, Norton's secretary Miss Honor Helfinger (Jane Roberts), Chickenman's mother Mildred Harbor (also Jane Roberts), and his girlfriend Sayde Leckner (Jane Roberts once again). Chickenman's mother sometimes helps out as the "Maternal Marauder" (also known as the "Masked Mother"). Chickenman roams Midland City seeking criminals in his yellow crime-fighting car, appropriately known as the Chicken Coupe. The program's music is borrowed; the introductory theme is taken from the James Bond classic "Thunderball", since the four-note trumpet sound fits perfectly with Benton Harbor's "Buck-buck-buck-buuuuuck" chicken call that precedes the title.
Chickenman's greatest foes include the Chicken-Plucker, the Dog Lady, Big Clyde Crushman, the Bear Lady, the Very Diabolical, Rodney Farber (a childhood playmate who never forgave Benton Harbor for breaking his red wagon one Christmas Day), and the Couple From SHTICK (Secret Henchmen To Injure Crime Killers). Benton Harbor is prone to spoonerisms, such as "I shall not rest while rime runs crampant in the streets of Midland City."
