Blackie "O"

Very un-PC:

Comedienne Joan Rivers revealed she once ditched a joke about First Lady Michelle Obama from her stand-up routine - because she feared she'd be accused of racism.

Recalling the wisecrack to shock Jock Howard Stern, the comedy legend said: "We used to have Jackie O now we have Blackie O!"

That should have sent the Obots into orbit, but since Rivers is a card-carrying member of the Progressive movement and the kinda- inner circle of Hollywood elites, all they could do was sputter a bit, wag a few fingers and dredge up a few lame excuses.

It's hilarious when one of their own sticks their foot in it.

But give Joan some credit for cajones... she must really dislike the woman to bring it up publicly, even in the guise of a "ditched joke".

Don't look for any White house invitations for Ms. Rivers. Dissing the "O" is political suicide... At least for now.
