Something is "funny" because there is an element of truth in it. I've no problem with the horse joke. It's as old as the hills. But, Mrs. Bush is certainly no desperate housewife. Mrs. Cheney certainly is not. And the thought of their attending a strip club with Condi, O'Connor and Ruth Buzzi is absurd. So, it really wasn't that funny. She may have bought some short term approval from the liberal glitterati, but she kind of drug her classy self through the mud a bit.
Of course it is. They can afford to have the strippers brought in for a private party.
