"Congratulations to Senator John McCain, the big winner in Florida. ... You know, this was what they call a GOP-only primary. So McCain had to win over a whole new voter group for him -- Republicans." --Jay Leno

"Congratulations to John McCain. He was a big winner up in New Hampshire. Fascinating comeback story, this John McCain, quite a guy. Highly decorated veteran. Spent five and a half years in prison then went into politics. Usually it's the other way around." --Jay Leno

"As you may have heard, John McCain's Straight Talk Express has hit some bumps in the road lately, and many of those bumps turned out to be former passengers. Last week, McCain's strategists Terry Nelson and John Weaver left the campaign. Then, on Monday, the senator lost communications director Brian Jones and deputies Matt Paul and Danny Diaz. I believe the McCain campaign now consists of the senator, his wife, and this guy they picked up hitch-hiking. Which is why, regrettably, I must formally announce that I, too, am leaving the McCain campaign. ... This is a decision made all the more difficult by the fact I never worked for the McCain campaign." --Stephen Colbert

But McCain just had to use the potty. ... McCain said he not only believes in evolution, he remembers it." --Bill Maher

"Senator John McCain moved to re-energize his presidential campaign with a speech to those for whom his politics are very personal -- the last uniformed Americans not deployed in Iraq, the cadets at the Virginia Military Institute. ... How committed is Senator McCain? [on screen: McCain saying, 'I would rather lose a campaign than a war.'] ... Luckily for Senator McCain, he might not have to choose." --Jon Stewart

"Big news from the 2008 presidential campaign. Last night, Senator John McCain -- right here on this program -- announced he's running for president. And then today, he shaved his head and checked into rehab." --David Letterman

"You heard about the big John McCain gaffe. He was on the David Letterman show announcing his presidential campaign, and he pulled a Joe Biden. ... He used the word 'wasted' to describe the lives lost in Iraq. Next day, he said he should have used the word 'sacrifice'. But to put it into perspective, when McCain was a prisoner in Vietnam, George Bush was wasted. Sorry, I meant to say he was sacrificing brain cells." --Bill Maher
