Question:
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.

Question:
Ernest Edward "Ernie" Kovacs (January 23, 1919 - January 13, 1962) was an American comedian, actor, and writer. Kovacs's visually experimental and often spontaneous comedic style influenced numerous television comedy programs for years after his death. Many individuals and shows, such as Johnny Carson, David Letterman, Rowan and Martin's Laugh-In, Saturday Night Live, Monty Python's Flying Circus, Jim Henson, Max Headroom, Chevy Chase, Conan O'Brien, Jimmy Kimmel, Captain Kangaroo, Sesame Street, The Electric Company, Dave Garroway, Uncle Floyd, and many others have credited Kovacs as an influence. Chevy Chase thanked Kovacs during his acceptance speech for his Emmy award for Saturday Night Live.
A frequent critic of the U.S. tax system, Kovacs owed the Internal Revenue Service several hundred thousand dollars in back taxes, due to his simple refusal to pay the bulk of them. Up to 90% of his earnings were garnished as a result. His long battles with the IRS inspired Kovacs to invest his money in a convoluted series of paper corporations in the U.S. and Canada. He would give them bizarre names, such as "The Bazooka Dooka Hicka Hocka Hookah Company". In 1961, Kovacs was served with a $75,000 lien for back taxes; that same day he bought the California Racquet Club with the apparent hope of being able to use it as a tax write-off. The property had mortgages at the time of purchase which were later paid by Edie Adams.  His tax woes also affected Kovacs's career, forcing him to take any offered work to pay his debt. This included the ABC game show Take A Good Look, appearances on variety shows such as NBC's The Ford Show, Starring Tennessee Ernie Ford, and some of his less memorable movie roles. He also filmed an unaired 1962 pilot episode for a proposed CBS series, Medicine Man (co-starring Buster Keaton, pilot episode titled "A Pony For Chris"). Kovacs's role was that of Dr. P. Crookshank, a traveling medicine salesman in the 1870s selling Mother McGreevy's Wizard Juice, also known as "man's best friend in a bottle". This was abandoned after his death, which occurred the day after filming some scenes for the pilot in Griffith Park. CBS initially intended to broadcast the show as part of a summer replacement program, The Comedy Spot, but decided against it due to problems with Kovacs's estate. The pilot is part of the public collection of the Paley Center for Media.  Some of the issues regarding Kovacs's tax problems were still unresolved years after his death. Kovacs had purchased two insurance policies in 1951; his mother was named as the primary beneficiary of them. The IRS placed a lien against them both for their cash value in 1961. To stop the actions being taken against her, Mary Kovacs had to go to Federal court. The court's early 1966 ruling resolved the issue, with the last sentence of the document reading: "Prima facie, it looks as if, within the limits of discretion permitted the government by the relevant statutes, an injustice is being done Mary Kovacs."  Adams, who married and divorced twice after Kovacs's death, refused help from celebrity friends who planned a benefit for the purpose. Saying "I can take care of my own children", and being determined to accept offers only from those who wanted to hire her for her talents, Adams managed to pay all of Kovacs' debts.
