It looks like there's another athlete who graduated from same charm school as Seattle Seahawks cornerback RIchard Sherman.Dutch speedskater Sjinkie Knegt was reportedly disqualified from a competition in Germany after he gave Olympic gold medalist Viktor Ahn of Russia a middle finger salute with both hands, according to The Independent. Ahn beat Knegt, capturing first place in the men's 500 meter final this weekend at the ISU European Short Track Speed Skating Championships, which took place in Dresden.While Ahn raised his hands with his index fingers in the air to celebrate his win, Knegt was right behind him, flipping the bird with both hands.The obscene gesture was captured by an Agence France-Presse photographer and the photo is making its round on news sites and social media.Knegt wasn't the only athlete making headlines this weekend for his display of questionable sportsmanship. The Seahawks' cornerback Richard Sherman went on a rant that was captured on-camera after his team beat the 49ers in the NFC's championship game.Photo Credit: AFP/Getty Images
