Bill Clinton on the Daily Show

ABC News’ Sunlen Miller reports: Marking his third appearance on The Daily Show with Jon Stewart former President Bill Clinton not only hawked his new book, "Giving:" but quickly got to pillow talk and naps.

Asked by Jon Stewart if he’d be able to handle the switch, from president to being the husband of a president, Clinton replied jokingly, "No, I may slit my throat," but was quick to get serious too, saying "my basic job will be to support her if she wins. Go and do what is most needed, and what is best for the country, let her make that call."

And what about advice over a little pillow talk if his wife is elected President? Clinton responded, "We’ve had an ongoing conversation for thirty-six years, and the truth is most couples in the White House have given each other advice on everything under the sun."

From campaign on the national level to campaigning on the state level, Clinton called on Congressional candidates to get more sleep, "I do believe sleep deprivation has a lot to do with some of the edginess of Washington today. And if we can find a way for them and their challengers  to run for elections without making them go out five nights a week for this endless hunt for funds….I think America would be better."

Jon Stewart, wrapping up Bill Clinton’s interview paraphrased, "President Clinton’s prescription for 21st Century America: "Giving" through charity and…naps."

To which the former president laughed and agreed, "And both will make you happy."
