Jesse Ventura, who said he was waterboarded as part of his military training, on whether torture works:

I'll put it to you this way: You give me a waterboard, Dick Cheney and one hour, and I'll have him confess to the Sharon Tate murders.

Jesse also suggested to Larry King that he would be a good choice for ambassador to Cuba, when we have one again.  As far as I know, the closest he has been to Latin America was in the first "Predator" movie, and he did pretty well there, at least for a while.
