Question: Who has played for more teams the original striker for FC Porto at the beginning of 2003-04 season or the player that replaced him? Passage:The 200304 season began with another 10 win over Uniao de Leiria, which gave the club its 13th Supertaca. Weeks later, Porto failed to repeat this result in the 2003 UEFA Super Cup, losing 10 to Milan. The departure of striker Helder Postiga was compensated by the signing of South Africa's Benni McCarthy, whose 20 league goals helped Porto in its league title defence and crowned him the competition's top scorer. Mourinho entered the 200304 UEFA Champions League with confidence to his team. Porto finished second in its group, losing only once to Real Madrid, and advanced to a round-of-16 meeting with Manchester United. Porto scored on the 90th minute of the second leg at Old Trafford to draw 11 and advance to the quarter-finals with a 32 aggregate win. The team then overcame Lyon and Deportivo La Coruna and reached the Champions League final, where it defeated Monaco 30 to lift the club's second European Champion Clubs' Cup. A 21 loss to Benfica in the Taca de Portugal final, held 10 days before, prevented another treble-winning season.

Question: Where was Billboard Frolics' creator born? Passage:Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What's Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky's Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".

Question: Did Park play longer for the Kyoto Purple Sanga or the PSV Eindhoven team? Passage:Park began his football career in his native South Korea and played for the Myongji University team before moving to Japan to play for Kyoto Purple Sanga. After Park's national team manager Guus Hiddink moved back to the Netherlands to manage PSV Eindhoven, Park followed him to the Dutch side a year later. After PSV reached the semi-finals of the 200405 UEFA Champions League, Park's talents were recognised by Manchester United manager Sir Alex Ferguson and he signed Park for a fee of around 4million in July 2005. In his time at United, Park won the Premier League four times and also won the 200708 UEFA Champions League and the 2008 FIFA Club World Cup. He moved to Queens Park Rangers in July 2012 after suffering a reduction in his number of appearances for Manchester United the previous season. However, an injury-interrupted season with QPR, combined with the club's relegation, led to Park rejoining PSV on loan for the 201314 season.
