Its because you dont know the background story of Streetfighter, heres a brief summary The two guys are Ken and Ryu, main characters of the SF games. Ryu spent many years living in the mountains, learning to ply his trade of packing home made fudge. Currently he lives the life of a hermit due to an accident many years ago when one of his apprentices (Ken) was killed in a tragic fudge packing accident (Ken slipped on some of Ryus hot fudge and fell off a cliff). Even though it was an accident Ryu swore to never put another apprentice's life in danger and decided that he would pack fudge solo for the rest of his life, he moved deeper into the mountains so nobody would find him and ask to be trained. Though unknown to Ryu, Ken never died from the impact, but he broke his back on the mountains. He waited at the cliff bottom for days in the hope that Ryu would come but he didnt. Instead he was found by a local lumberjack, who rescued Ken and taught him the art of Iron Fist, bad hairstyles, and being able to stay warm in the mountains wearing nothing but briefs, this man was Zangief. Ken, sets off on a journey to get revenge over Ryus apparent abandoning of him. He soon finds Ryus hidden log cabin and Ken decides that he needs to repay his old master Ryu the favour. Thats where this clip comes in.
