McCain jokes it up on SNL

Republican John McCain poked fun at his presidential campaign's financial shortcomings in an appearance on NBC's "Saturday Night Live."

The presidential hopeful made a cameo appearance on the show with Tina Fey reprising her impersonation of Alaska Gov. Sarah Palin.

The two said they couldn't afford a half-hour campaign commercial on network television like Democrat Barack Obama aired earlier this week. They said they'd sell campaign products on the QVC shopping channel instead.

Among other things, McCain advertised a set of knives to cut "tough pork" in Washington, while Fey, as Palin, advertised a set of "Joe" dolls commemorating Joe the Plumber, Joe Six Pack and Democratic rival Joe Biden.

The pretend Palin said she wouldn't be returning to Alaska after the election. "I'm either running in four years or I'm going to be a white Oprah," she said.
