Bieber said, "It's really awesome to be able to work with professional dancers, you know, people that were in, like, ABDC, and also got an approval from choreographer Jamaica, who said Bieber was "killing it" and that she didn't have to give him any corrections. It made its premiere during the June 17, 2010 results show of the seventh season of So You Think You Can Dance, and was introduced by Usher after his performance of "OMG".

Singer/actress and model Katerina Graham makes a cameo in a scene with Poreotics. Bieber's best friend Ryan Butler, who appeared in the "One Time" video, also appears alongside Bieber, wearing a T-shirt advertising his Twitter account. According to Tamar Antai of MTV News the video "makes vague allusions" to clips for Busta Rhymes' "Pass the Courvoisier, Part II" and Chris Brown's "Wall to Wall".

Input: Consider Input: Question: Who was held responsible for Charles George Gordon's death? Passage:In 1889 de Morès joined La Ligue antisémitique de France (Antisemitic League of France) founded by Edouard Drumont. After more verbal attacks on Jews, he went to Algeria to strengthen the French hold there and stop British advances into the interior of Africa. He used anti-Semitic rhetoric to his advantage in Algeria, giving speeches claiming that French and African Jews and the British were conspiring to conquer the entire Sahara Desert. With the British in a difficult position in the Sudan after the death of General Charles George Gordon in the siege of Khartoum, de Morès planned a trip there to meet with the Mahdi, a powerful Muslim leader who was intent on undermining British hegemony in the region. He traveled to North Africa, selected Arabic men in Tunis to escort him, and set out his caravan towards Kebili.



Output: With the British in a difficult position in the Sudan after the death of General Charles George Gordon in the siege of Khartoum, de Morès planned a trip there to meet with the Mahdi, a powerful Muslim leader who was intent on undermining British hegemony in the region
