What is the meaning of the Young Sheldon title sequence?
The background shows mountains and a desert, whilst the foreground has Sheldon (usually in bowtie, checked shirt, shorts and cowboy boots) walking out, standing triumphantly, before he notices a cow and backs away from it, before resuming his triumphant look as the logo appears and pans to the sky. 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 Einstein, an astronaut and a train engineer
Why it was chosen? Is it a tribute to the old series? Is there any significance for the subtle changes in the sequence (for example showing specific member in addition)?
I found a similar question without any real answer.
EDIT
Found in IMDB it's a parody on Walker, but I don't see it and don't know the reference
The show's intro is a parody of Walker, Texas Ranger (1993)
I'm asking especially because the show itself is very funny, while the intro sequence seems redundant
Found more differences
At least one episode opening per season is slightly different from the usual opening of Sheldon walking up, taking a superhero stance, then moving over slightly as a cow approaches. In season one, a tumbleweed rolls by, making him jump out of the way. In season two, the camera does a 360 around him.
Beginning with Season 5, the rest of the family no longer looks at him puzzled when he walks up, but the animal they move away from changes from a cow to a bull.
