'The Daily Show' (weekdays, 11PM ET on Comedy Central) has been having a lot of fun over the last year with some of the more eccentric potential Republican candidates for president, such as Sarah Palin, Newt Gingrich, Michele Bachmann and now Donald Trump.

However, on Tuesday, Jon Stewart got some news that sent a chill down his comedic spine: Mitt Romney has launched an exploratory committee into a presidential run.

"No, not Captain Buzzkill!" Stewart shrieked. "Not the guy who looks like everyone who ever fired your dad. He's gonna suck all the fun right out of this crazy thing!"

"Look at the online video announcing his run: It looks like it could double as an ad for erectile dysfunction," Stewart continued, proving that he could still have some fun with Romney.

And as long as Romney maintains his middle-aged-catalog-model looks, Stewart can easily just recycle that same joke using Lipitor or some kind of high-fiber food stuff as the punch line.
