The show's title sequence is played to Steve Burns ' "Mighty Little Man", the first track from his 2003 album Songs for Dustmites. The background in the first two seasons shows mountains and a desert, whilst the foreground has Sheldon (usually in bow tie, checked shirt, shorts and cowboy boots) walking out, standing triumphantly, noticing a cow, and backing away from it before resuming his triumphant look as the logo appears and tilts to the sky. Occasionally, a tumbleweed appears, instead of the cow. The title sequence was changed from Season 3 onwards to include the entire Cooper family, as well as showing Sheldon in different costumes, such as Albert Einstein, Mr. Spock, The Flash, an astronaut, and a train engineer. Season 5 features a black bull in place of the cow. In Season 7, the title sequence was slightly changed to include Mandy & CeeCee. The Cooper Family doesn't walk away from the bull. Instead, Georgie shoos the bull away.
