I noticed this, but even without race and gender the characters are profoundly stereotyped—intentionally exaggerated for effect. At least, I hope there aren't real-life Certified Red Line Experts running around, nor designers hoping to draw red lines in green ink… Taken too literally, this sketch could be offensive to all of women, portrayed as clueless; male executives, portrayed as willfully ignorant and over-demanding; Asians, portrayed as obviously engineers; non-Asians, portrayed as obviously not engineers; engineers, portrayed as incapable of working backwards from impossible requirements to find a solution that actually works; and probably other groups I've forgotten.
