I am as frustrated with society as a pyromaniac in a petrified forest.

The line is a comic simile that frames social frustration as thwarted impulse: a pyromaniac wants to burn, but a petrified forest—turned to stone—cannot catch fire. Brown’s joke suggests the speaker feels surrounded by a society that is inert, unresponsive, or impervious to change, making any attempt to provoke reaction feel futile. The humor comes from the exaggerated, slightly transgressive image (a pyromaniac) paired with an impossibility (burning stone), turning alienation into a vivid one-liner. It also hints at a critique of social rigidity: when institutions and norms are “petrified,” even disruptive energy can’t produce transformation.
