Undecided voters attending the second presidential debate between Barack Obama and Mitt Romney on Oct. 16 at Hofstra University may want to press the candidates on the economy, jobs and international affairs; however, those voters have incentive to ditch their hard-hitting questions for an offbeat one: whether Obama and Romney prefer sausage or pepperoni on their pizza.

Should any questioner have no shame and go ahead with that query, Pizza Hut will reward them with free pizzas for life as part of a promotion.

"We recognize there are a lot of serious issues to be debated, but we also know a lot less serious -- but no less important -- ones are being discussed every night inside houses across the country," Kurt Kane, chief marketing officer, of Pizza Hut, said in a statement. "So for the candidates to be able to show that they're in tune with all the issues, we felt a pizza-related question on behalf of the Pizza Party was very appropriate for a town hall debate."

The second presidential debate’s format is a shake-up of the first held last week at the University of Denver.

Instead of a moderator asking questions, the second debate in central Long Island is a town-hall-style format, with questions coming from undecided voters selected by the Gallup Organization, according to the Commission on Presidential Debates.

Romney was declared the clear winner in last week’s debate, moderated by Jim Lehrer, with Obama’s performance criticized as lackluster.

Candy Crowley of CNN will serve as moderator for the second debate at Hofstra.

“Candidates each will have two minutes to respond [to questions,] and an additional minute for the moderator to facilitate a discussion,” according to the commission.

While the sausage or pepperoni question will certainly be out of left field if it is asked, there is precedent for oddball questions in presidential debates.

Although it wasn’t an official debate, MTV held a forum in 1994 in which Bill Clinton was asked whether he wears boxers or briefs.

“Usually briefs,” Clinton responded.

The second presidential debate will be preceded Thursday night by the first and only vice presidential debate between Joe Biden and Paul Ryan at Centre College in Danville, Ky. Both debates are scheduled to begin at 9 p.m. ET. Martha Raddatz, ABC News Chief Foreign Correspondent, will moderate the vice presidential debate.
