input: The duo of Leander Paes and Mahesh Bhupathi were nicknamed the ''Indian Express''. Leander Paes' off-and-on partnership with Bhupathi drew constant media attention in their home country India. In the 2006 Asian Games, a loss to the Chinese Taipei team in the team event led Leander to question Bhupathi's commitment to Team India. He once stated in an interview that although he and Bhupathi are friends, he did not consider pairing with his former teammate. However, for the 2008 Beijing Olympics, they decided to play together for their country, and lost in the quarterfinals to the eventual champions Roger Federer and Stanislas Wawrinka.  In 2011, the "Indian Express" pair won the doubles title at Chennai Open. They reunited to play in a Grand Slam Tournament after nine years and claimed runners-up in the 2011 Australian Open and reached the semifinals in the year-end championships.  The Indian duo has a 303-103 career record together. They have a higher success rate against various top teams. They have a Davis Cup record of longest winning streak in doubles, with 24 straight wins.  Leander Paes was paired with Vishnu Vardhan at the London Olympics 2012, following the refusal of Mahesh Bhupathi and Rohan Bopanna to play with him at the Olympics. Paes threatened to withdraw from the Olympics rather than play with Vardhan, whose world ranking was 296, but withdrew the threat a week later. Paes and Vardhan reached the second round of the tournament, losing to eventual silver medalists Michael Llodra and Jo-Wilfried Tsonga of France.

Question: Winchell was born Paul Wilchinsky in New York City on December 21, 1922, to Solomon Wilchinsky and Clara Fuchs. His father was a tailor; his grandparents were Jewish immigrants from Russian Poland and Austria-Hungary. Winchell's initial ambition was to become a doctor, but the Depression wiped out any chance of his family's ability to afford medical school tuition. At age 13, he contracted polio; while recovering, he happened upon a magazine advertisement offering a ventriloquism kit for ten cents.

Winchell's career after 1968 included various voice roles for animated television series. For Hanna-Barbera, he played the character Dick Dastardly in multiple series (including Wacky Races and Dastardly and Muttley in their Flying Machines); Clyde and Softy on Wacky Races and The Perils of Penelope Pitstop; and Fleegle on The Banana Splits Adventure Hour, and Gargamel on The Smurfs.  He also provided the voice of Bubi Bear in Help!... It's the Hair Bear Bunch! in 1971, the voice of Revs on Wheelie and the Chopper Bunch, as Moe on The Robonic Stooges (a role he previously played on The New Scooby Doo Movies), and Shake on The CB Bears. In 1973, he did the voice of Goober the Dog on the H-B show Goober and the Ghost Chasers and also guest starred as the rain-making villain on an episode of Hong Kong Phooey. For Disney, Winchell voiced Tigger in Disney's Winnie-the-Pooh featurettes, and won a Grammy Award for his performance in Winnie the Pooh and Tigger Too.  Beginning with the television series The New Adventures of Winnie the Pooh, he alternated in the role with Jim Cummings, the current voice of Pooh. Winchell's final performances as Tigger were in 1999 for Winnie the Pooh: A Valentine for You and The Many Adventures of Winnie the Pooh attraction at Walt Disney World. Following his retirement, Cummings permanently took over the role of Tigger starting with Sing a Song with Pooh Bear in 1999 (though some of Winchell's vocals from previous Pooh animations were included). Other Disney roles included parts in The Aristocats as a Siamese cat named Shun Gon, and The Fox and the Hound as Boomer the woodpecker. He was also the original voice of Zummi Gummi on the TV series Disney's Adventures of the Gummi Bears for seasons 1-5; Jim Cummings took over for the final season in 1990.  Winchell provided the voices of Sam-I-Am and the unnamed character Sam pesters in Green Eggs and Ham from the animated television special Dr. Seuss on the Loose in 1973. He played Fleabag on The Oddball Couple, Fearless Freddy the Shark Hunter on the Pink Panther spin-off Misterjaw in 1976, as well as a number of one-shot characters in The Blue Racer series. In commercials, he voiced the character of Burger Chef for the fast food chain of the same name, the Scrubbing Bubbles for Dow Chemicals and Mr. Owl for Tootsie Roll Pops.  From 1981-89, Winchell voiced Gargamel on The Smurfs as well as on several Smurfs television movies. During the 1980s, he was called upon by Hanna-Barbera to reprise his role of Dick Dastardly on Yogi's Treasure Hunt (which was a tour-de-force featuring all of the H-B characters) and later on Wake, Rattle and Roll (which was a Wacky Races spin-off). Also on the animated movie Yogi Bear and the Magical Flight of the Spruce Goose, he did the voice of the Dread Baron, who was previously voiced by John Stephenson on the Laugh-a-Lympics.
