UPDATE: Video is being taken down from most sites due to the nudity and the news station probably not being too proud of their mistake...but, Deadspin has it.
The TV station, Fox 31 in Denver, has released an apology saying that the inadvertent penis did not 'come from the tablet many viewers saw being used by one of our anchors.'
Not sure if that makes it any better to know that it was from the control room and not from an actually anchor on air.
The Denver news station was scrolling on a computer looking for pictures of the Seattle helicopter crash and a penis was accidentally aired live.
Obviously, super NSFW video here. EXPLICIT - 18 and over due to male nudity
