"Prayer really does work!" Jon Stewart announced on Thursday night's "Daily Show."
Stewart was thrilled to hear the news that former Texas governor Rick Perry is running for president again. Or, as Stewart called him, "the guy who 'Oopsed!' himself out of the 2012 race."
"We must do right, and risk the consequences," Perry said in his announcement video.
"Risk the consequences -- maybe the most accurate campaign slogan I've ever heard," Stewart said. "That's the same slogan you use to advocate unprotected sex."
Stewart also took a look at the newly announced Democratic contender, Lincoln Chafee, who he mocked for making a conversion to the metric system part of his campaign, a well as Jeb Bush, who still technically isn't a candidate.
