The best late-night TV joke Wednesday might have been delivered by Sarah Palin.
"Do you know what the difference is between a hockey mom and a pit bull?" the Republican vice-presidential candidate asked during a speech that pushed well past prime time. "Lipstick."
Certainly that quip brought more raucous cheers than were mustered by any of the talk-show hosts, who were handcuffed because they taped their programs before Palin delivered her speech.
That meant that NBC's Jay Leno and CBS' David Letterman could only act as though the speech was a thing of the past.
"I gotta admit she looked very comfortable at the podium," Leno said, "because it's kind of like Alaska. When you look over the convention floor, there's nothing but white as far as the eye can see."
Letterman said, "Sarah Palin gave a tremendous speech at the convention tonight -- although some are claiming that it was her daughter's speech."
Only ABC's Jimmy Kimmel worked in wisecracks pegged to Wednesday's actual happenings:
• "They even brought along the high-school kid who knocked their daughter up. His name's Levi Johnston. That's gotta be a fun trip for him."
