CNN on Sunday failed to check the credentials of someone who said he was a San Francisco Police Department official, and then said that the recent earthquake was a "rumbling from Howard Stern's butt crack."

Just hours after a magnitude 6.0 earthquake rocked the Napa Valley region of California, a CNN host introduced someone named "Adam Sure" as the "PIO of the San Francisco police."

"Adam, what kind of calls are you getting right now?" the host wondered. "Any damage? Any injuries?"

"Yes, because of the early morning, most people were home when it occurred," the alleged police official remarked. "And what we believe is that this was a rumbling from Howard Stern's butt crack."

"Obviously, that is not who we expected it was to be," the CNN host explained. "We apologize for that so early in the morning."

"The fact of the matter is, this is a serious situation. So, we don't need any jokes going on right now."
