You didn't think Joan Rivers would let Fergie get away with that unzipped dress did you?

The Fashion Police host is on a roll regarding the singer's Jean-Charles de Castelbajac frock:

"I'm gonna quote the late Johnny Cochran, 'If the dress don't fit, you look like s--t,'" she quipped in an unused bit from tonight's show. 

And that's not all. The hostess with the mostest also covers skunk stripes, sexy road maps and more!

So click in and get all of Joan's jokes that didn't make it on air in our sassy sartorial photo gallery.
