IN: Paul Reubens (ne Rubenfeld; born August 27, 1952) is an American actor, writer, film producer, game show host, and comedian, best known for his character Pee-wee Herman. Reubens joined the Los Angeles troupe The Groundlings in the 1970s and started his career as an improvisational comedian and stage actor. In 1982, Reubens put up a show about a character he had been developing for years.

Reubens auditioned for Saturday Night Live for the 1980-1981 season, but Gilbert Gottfried, who was a close friend of the show's producer and had the same acting style as Reubens, got the place (ironically, Gottfried would later get in trouble for joking about Reubens' indecent exposure arrest as an award presenter at the Emmys). Reubens was so angry and bitter that he decided he would borrow money and start his own show in Los Angeles using the character he had been developing during the last few years, "Pee-wee Herman". With the help of other Groundlings like John Paragon, Phil Hartman and Lynne Marie Stewart, Pee-wee acquired a small group of followers and Reubens took his show to The Roxy Theatre where "The Pee-wee Herman Show" ran for five sellout months, doing midnight shows for adults and weekly matinees for children, moving into the mainstream when HBO aired The Pee-wee Herman Show in 1981 as part of their series On Location. Reubens also appeared as Pee-wee in the 1980 film Cheech & Chong's Next Movie. Although it was Reubens in the role of Pee-Wee, the end credits of the movie billed him as Hamburger Dude. Reubens' act had mainly positive reactions and quickly acquired a group of fans, despite being described as "bizarre", and Reubens being described as "the weirdest comedian around". Pee-wee was both "corny" and "hip", "retrograde" and "avant-garde". When Pee-wee's fame started growing, Reubens started to move away from the spotlight, keeping his name under wraps and making all his public appearance and interviews in character while billing Pee-wee as playing himself; Reubens was trying to "get the public to think that that was a real person". Later on he would even prefer his parents be known only as Honey Herman and Herman Herman. In the early and mid-1980s, Reubens made several guest appearances on Late Night with David Letterman as Pee-wee Herman which gave Pee-wee an even bigger following. During the mid-1980s, Reubens traveled the United States with a whole new The Pee-wee Herman Show, playing notably at the Guthrie Theater in Minneapolis, Caroline's in New York City and, in 1984, in front of a full Carnegie Hall.

input: The Joker debuted in Batman #1 (Spring 1940) as the eponymous character's first villain, shortly after Batman's debut in Detective Comics #27 (May 1939). The Joker initially appeared as a remorseless serial killer, modeled after a joker playing card with a mirthless grin, who killed his victims with "Joker venom": a toxin which left their faces smiling grotesquely. The character was intended to be killed in his second appearance in Batman #1, after being stabbed in the heart. Finger wanted the Joker to die because of his concern that recurring villains would make Batman appear inept, but was overruled by then-editor Whitney Ellsworth; a hastily drawn panel, indicating that the Joker was still alive, was added to the comic. The Joker went on to appear in nine of Batman's first twelve issues. The character's regular appearances quickly defined him as the archenemy of the dynamic duo, Batman and Robin; he killed dozens of people, and even derailed a train. By issue #13, Kane's work on the syndicated Batman newspaper strip left him little time for the comic book; artist Dick Sprang assumed his duties, and editor Jack Schiff collaborated with Finger on stories. Around the same time, DC Comics found it easier to market its stories to children without the more mature pulp elements that had originated many superhero comics. During this period, the first changes in the Joker began to appear, portraying him more as a prankster than threat; when he kidnaps Robin, Batman pays the ransom by check, meaning that the Joker cannot cash it without being arrested. Comic book writer Mark Waid suggests that the 1942 story "The Joker Walks the Last Mile" was the beginning point for the character's transformation into a more goofy incarnation, a period that Grant Morrison considered lasted the following thirty years. The 1942 cover of Detective Comics #69, known as "Double Guns" (with the Joker emerging from a genie lamp, aiming two guns at Batman and Robin), is considered one of the greatest superhero comic covers of the Golden Age and is the only image of the character using traditional guns. Robinson said that other contemporary villains used guns, and the creative team wanted the Joker--as Batman's adversary--to be more resourceful.
