a converted stage in Hoch Auditorium with a seating capacity of 5,500. In response to the construction of Ahearn, the University of Kansas successfully lobbied the Legislature to approve the construction of Allen Fieldhouse, which would seat 17,000. KU opened the facility with a 77–66 victory over Kansas State on March 1, 1955. This period also saw the beginning of the 'Sunflower Doubleheader', with two non-conference teams visiting the state to play KU and K-State at one venue one night, then switching venues and opponents the following evening. This event was held from 1957 to 1968, and featured national powerhouses such as UCLA, Xavier, San Francisco, St. Joseph's, Cal, and Marquette. 1960s and 1970s The basketball rivalry between the two schools continued unabated through the 1960s and 1970s, with the two schools competing annually for the Big Eight Conference championship (see chart below). In Dick Harp's last two seasons as the KU coach, the Jayhawks plummeted to losing records of 7–18 in 1962 and 12–13 in 1963. Nevertheless, in the championship game of the Big Eight Holiday Tournament in December 1962, KU posted a surprising 90-88 quadruple-overtime victory over K-State. Also, on February 20, 1965, one of the classic pranks in the series was perpetrated when a pair of 6x12 banners saying "Go Cats, Kill Snob Hill Again" unfurled on the east and west sides of the Allen Fieldhouse scoreboard with eight minutes left in the first half. Unfortunately for the Cats, this did not come to pass, as KU beat K-State 88–66. Another popular "prank" perpetrated by Kansas State students throughout the years is throwing live chickens, painted blue and red, on the court during pre-game introductions, as a taunt at the Kansas mascot, the Jayhawk. For years the Kansas State administration has attempted to stop this practice, and following a nationally televised game on February 19, 2007, PETA complained about it in a letter to KSU President Jon Wefald. 1980s The 1980s saw the return of star power to the schools and arguably the rivalry's most high-profile game. At the start of the decade, Rolando Blackman at Kansas State and Darnell Valentine at KU squared off in some classic match-ups. To close the decade, it was Mitch Richmond (K-State) and Danny Manning (KU) battling. With Richmond and Manning in their senior years, the 1987–1988 season proved to be eventful in the rivalry. In the first matchup of the
