John Kerry was on a comedic roll during his DNC speech Thursday night. Once accused of being a flip-flopper himself, he called out Romney saying he "doesn't have an opinion on Iraq and Afghanistan, he has every position!" Kerry called Romney and Ryan "the most inexperienced foreign-policy twosome to run for president and vice president in decades," and joked that, "for Mitt Romney, an overseas trip is what you call it when you trip all over yourself overseas." And the comedy from the once-stiff candidate didn't stop there. "Sarah Palin said she could see Russia from Alaska. Romney talks like he's only seen Russia from watching Rocky IV," Kerry joked.
