Late Night Highlights: Will Ferrell Talks Halloween, Sings Celine Dion

The Rally to Restore Sanity and/or Fear is finally upon us and to prepare, Jon Stewart welcomed all of his correspondents to D.C. last night -- even the one that hitched a ride with Jerry Stiller and Anne Meara. Meanwhile, Will Ferrell talked Halloween and sang Celine Dion, Jimmy Fallon went to a gay bar, Dana Carvey remembered the time Keith Richards talked to a horse and Stephen Colbert confronted his fears by talking to a homosexual.

Before this weekend's D.C. Rally to Restore Fear, Stephen Colbert faced off against his fears, literally -- by talking to a gay man, a Mexican and a possible robot.

3. Head Swap

Seriously, I have no idea how you even categorize last night's Head Swap segment in which Jimmy Fallon sang a song about how photoshopping celebrity heads led to a night in a cowboy costume at a gay bar.

Last night, all of The Daily Show correspondents finally made it to D.C. for this weekend's Rally to Restore Sanity. For Wyatt Cenac, that meant getting a ride with a combative celebrity couple in a Subaru.
