Like John Waters' shock-value comedies of yore, Family Guy keeps moving the taste-be-damned line. "You laughed at that" these episodes spanning seasons six and seven challenge viewers. "Okay, then laugh at this!" AIDS, cancer, incest, September 11, and the films of Matthew McConaughey are all grist for the mill. Though it has taken its lumps from the South Park contingent, Family Guy merrily stays true to its absurdist, arbitrary muse.
