IN: Comet is the name of two fictional comic book characters owned by DC Comics whose adventures have been published by that same company. The first character was a sapient horse with magical powers who was once a centaur in ancient Greece. The second character is a shapeshifter with three forms (male, female, and winged centaur). Both characters are connected to the Superman family of titles.

Comet the Super-Horse is a fictional character that appears in comic books published by DC Comics. Comet was introduced in the Superboy story in Adventure Comics #293 in February 1962, then appeared regularly with Supergirl beginning in Action Comics #292 in September 1962.  Comet was one of a series of super-powered animals, including Streaky the Supercat and Beppo the Supermonkey, that were popular in DC's comics of the 1960s. Comet was Supergirl's pet horse and, while in his human form as Bill Starr, her brief boyfriend. Comet also had a brief romance with Lois Lane in her comic book.  As he described to her telepathically, he was originally a centaur in ancient Greece named Biron. The witch Circe gave him a potion to turn him fully human after he prevented an evil sorcerer poisoning her water, but by mistake made him fully horse instead due to the Sorcerer. Unable to reverse the spell, she instead gave him superpowers, including immortality. The Sorcerer asked his teacher to help him against Biron and they were able to imprison him on an asteroid in the constellation of Sagittarius, which he had been born under. However, when Supergirl's rocket passed, it broke the force field, enabling him to escape. Later, after meeting Supergirl, he went on a mission with her to the planet Zerox, where a magic spell was cast that turned him into a human, but only while a comet passes through the solar system he is in. As a human, he adopted the identity of "Bronco" Bill Starr, a rodeo trick-rider, whom Supergirl fell in love with.  Comet made sporadic appearances in comic stories through the 1960s, and even became a member of the Legion of Super-Pets, a group consisting of the aforementioned super-powered animals.  A traditional equine Comet is partially seen in Legion of Three Worlds #1. He is part of a display in the museum Superboy-Prime visits. The museum does have displays of the supermen of the multiverse and the Kristen Wells Superwoman so it is unclear whether this means Comet has returned to regular continuity.

input: Martin attracted the attention of Metro-Goldwyn-Mayer and Columbia Pictures, but a Hollywood contract was not forthcoming. He met comic Jerry Lewis at the Glass Hat Club in New York, where both were performing. Martin and Lewis formed a fast friendship which led to their participation in each other's acts and the formation of a music-comedy team. Martin and Lewis's debut together occurred at Atlantic City's 500 Club on July 24, 1946, and they were not well received. The owner, Skinny D'Amato, warned them that if they did not come up with a better act for their second show that night, they would be fired. Huddling in the alley behind the club, Lewis and Martin agreed to "go for broke", they divided their act between songs, skits, and ad-libbed material. Martin sang and Lewis dressed as a busboy, dropping plates and making a shambles of Martin's performance and the club's decorum until Lewis was chased from the room as Martin pelted him with breadrolls.  They did slapstick, reeled off old vaudeville jokes, and did whatever else popped into their heads. The audience laughed. This success led to a series of well-paying engagements on the Eastern seaboard, culminating in a run at New York's Copacabana. The act consisted of Lewis interrupting and heckling Martin while he was trying to sing, with the two ultimately chasing each other around the stage. The secret, both said, is that they ignored the audience and played to each other. The team made its TV debut on the first broadcast of CBS-TV network's The Ed Sullivan Show (then called "The Toast Of The Town) on June 20, 1948, with composers Rodgers and Hammerstein also appearing. Hoping to improve their act, the two hired young comedy writers Norman Lear and Ed Simmons to write their bits. With the assistance of both Lear and Simmons, the two would take their act beyond nightclubs.  A radio series began in 1949, the year Martin and Lewis signed with Paramount producer Hal B. Wallis as comedy relief for the movie My Friend Irma. Their agent, Abby Greshler, negotiated one of Hollywood's best deals: although they received only $75,000 between them for their films with Wallis, Martin and Lewis were free to do one outside film a year, which they would co-produce through their own York Productions.  They also controlled their club, record, radio, and television appearances, and through these they earned millions of dollars. In Dean & Me, Lewis calls Martin one of the great comic geniuses of all time. They were friends, as well, with Lewis acting as best man when Martin remarried in 1949. But harsh comments from critics, as well as frustration with the similarity of Martin and Lewis movies, which producer Hal Wallis refused to change, led to Martin's dissatisfaction. He put less enthusiasm into the work, leading to escalating arguments with Lewis. Martin told his partner he was "nothing to me but a dollar sign". The act broke up in 1956, 10 years to the day from the first teaming.
