Bad Teacher's humor, while amusing, rarely executes anything more clever than simplistic immaturity, wherein any teacher who says "fuck" is inherently hilarious, and sexy ladies can effortlessly trick men while taking on fatties as abused sidekicks, because that's just how the world of cinema works.
