The Knowledge Rules tee design is for the Breaking Bad,The Big Bang Theory and Game of Thronesfans and anyone who likes or gets the "The Good, The Bad, The Ugly" reference as well.
This concept is a parody of "The Good, The Bad, The Ugly" only with who knows what from other franchises. Walter White aka Heisenberg of Breaking Bad "Knows Chemistry", Dr. Sheldon Cooper of The Big Bang Theory "Knows Physics" and the bastard Jon Snow "Knows Nothing". I must say that it is cool as Hell to have these four completely different fandoms all on one tee. The theme of Knowledge is the only way that I could see it done too so kudos RicoMambo.
As for the artwork, while the layout is derivative, the art features monochromatic green portraits with awesome shading provide great character likenesses based on actual video stills. Each franchise's text is also done in their own stylized title fonts.
Like other Breaking Bad or even Game of Thrones tees. I wouldn't recommend it as a school garment as it's not appropriate for kids.
Wear this tee to a Comic-Con or wherever you'd like to stir up a conversation about any of the shows.
