U.S. Sen. Al Franken (D-Minn.) made a career of making people laugh when he was a writer and actor on "Saturday Night Live." He also made some of us laugh and think with his books, including, "Rush Limbaugh Is a Big Fat Idiot and Other Observations."

In 2008, he won a seat in the U.S. Senate and is now on the Senate Judiciary Committee where members are taking up the Defense of Marriage Act and the new pro-gay bill, the Respect for Marriage Act.

Watch below as Franken crushes Tom Minnery,  the executive director of CitizenLink, a public policy division of that not-so-funny and very anti-gay Focus on the Family, during the hearings on July 20. Minnery cites a federal study that he says straight couples are the best kinds of parents. Well, Franken said he actually read the study.
