***UPDATE*** [October 2, 11:50 ET]: NBCNews.com has apparently taken down the offenisve cartoon series, but it can still be found here (h/t TVNewser).
In a brazen attack on Fox News, NBCNews.com published a 15-image slideshow compiled by the website's political cartoonist Daryl Cagle ripping the cable channel. One cartoon shows a man sitting in a recliner with a remote as Fox News emanates from an elephant's rear end. In another, Fox was again depicted as an elephant, this time with a pile feces behind it labeled "Secret corporate money."
MediaBistro's TVNewser blog caught the sleazy display on the network news site, with writer Alex Weprin observing: "It is somewhat unusual for a news organization to publish such a sloppy item trashing a competitor."
