“They’re saying that when Sarah Palin is speaking, she blinks her eyes. People believe that those are coded messages, and I’m a conspiracy nut, so I got a hold of a tape of a recent campaign appearance, and I slowed it down. And if you translate the blinks to Morse code, sure enough, right there it says, ‘Vote for Grandpa.’”  (John P. Filo / Associated Press)

Stephen Colbert, on ‘The Colbert Report,’ Oct. 16

“John McCain brought the heat, which is good, because it helps his lower back.”  (Alex Oliveira / Associated Press)

Conan O’Brien, on ‘Late Night with Conan O’Brien,’ Oct. 16

“And more details coming out about Joe the Plumber. This is true. I’m not making this up. It came out this morning. His real name is not Joe, and he’s not a licensed plumber. That’s true. However, the McCain campaign insists that the ‘the’ is accurate. That part’s true.”  (Mark J. Terrill / Associated Press)

Jon Stewart, on “The Daily Show with Jon Stewart,” Oct 16

Jay Leno, on ‘The Tonight Show with Jay Leno,’ Oct. 15
