Sometime comedienne Joan Rivers raised eyebrows – though of course not her own, being immovable and all – when she hurled a curse word at herself on live TV Wednesday morning.

Dropping by Fox News Channel’s ‘Fox & Friends‘ morning talker to pimp her ‘How’d You Get So Rich?’ series, Rivers chided herself for never seizing on a get-rich-quick scheme.

“I go home, I spit on my furniture, I go home I hit myself on the head – ‘I didn’t think of a pet rock, you stupid bitch,’” she related.

Rivers’ B-bomb was met with a chorus of startled whoas, with one ‘F&F’ cohost reminding her, “You can’t say that on morning TV.”

As if ‘Fox & Friends’ regrets scoring an easy headline here during May sweeps.
