"The Daily Show's" Jon Stewart entered the proverbial lion's den, appearing live on Fox News Sunday to debate "media bias" with host Chris Wallace.

Early in the interview, Wallace flashed a previous quote of Stewart's calling Fox News a "relentless agenda-driven 24 hour news opinion propaganda delivery system," and asked Stewart, "Where do you come up with this stuff?"

Stewart responded, "Uh, it's actually quite easy."
