Roundup: Funniest YouTube Questions for Candidates

More than 600 video questions for Democratic presidential candidates have been submitted to YouTube -- mostly on serious topics like health care, immigration, education, global warming, and other timely and important topics.

However, as CNN culls through the videos to choose questions for its July 23 debate, it's also finding that some questioners are using humor -- in many cases, quite well -- to get their points across.

One question, for example, is set to music and asks about how candidates will tackle tax rates. And Jackie and Dunlap from Murfreesboro, Tenn., fret over the attention former vice president -- and noncandidate -- Al Gore is getting from the media, and quiz John Edwards on his attractiveness in their "Red State Update."

Others use humor to pose questions on who the candidates may pardon and whether they would force the government to disclose information on UFOs.
