Hard questions for the candidates

Having read voluminous commentary on last night's Dem debate, I opted not to seek a transcript.

From what I can gather, Sen. Clinton performed well, Sen. Obama less so, and the moderators both were the big losers.

George Stephanopoulos apparently responded to criticism by stating that they simply asked the candidates "hard questions".

Hoping that there'll be no more Dem debates, I here suggest some "hard questions" for the candidates in the general election debates:

For Sen. McCain: Is the Riemann Hypothesis true? Is it provable? If not, can you provide a counterexample?

For Sen. X (Clinton/Obama): Is there an odd perfect number? If yes, in what way is it related to Mersenne primes? If not, what are the implications for the truth-value of the Riemann Hypothesis?

For Sen. McCain: If you had to choose, would you prefer to strip & masturbate on national television, or fellate Osama bin Laden in private?

For Sen. X (Clinton/Obama): same question.

These seem like appropriately hard questions that'll catch the candidates off guard and help the electorate make a choice between 'em.
