Are we sick of Sarah Palin jokes yet? Yes—yes we do believe we are, yet not since Brokeback Mountain has a single cultural phenomenon offered comedy writers (and ankle-shackled galley bloggers) such a bounty of low-hanging fruit.And—much like the gay-cowboy motif into its third month of YouTube mashups—just when you think you've snorted out your last nose-chuckle at the congenial flautist's antics, along comes one more to tickle your funny places. We offer as evidence the recent (OK, fine, it ran a week ago, but we're having trouble staying up past 9 p.m. lately) appearance of Betty White on Late Late Show with Craig Ferguson, in which she affected the guise of a speech writer for superannuated candidate John McCain. The money shot, of course, is her succinct assessment of his running mate—"That is one crazy bitch!"—before segueing into a lip-smacking meditation on the Democratic challenger that almost makes us wonder if the former Golden Girl hasn't been lingering in the far corners of Craigslist lately.
