Rand Paul mentions non-human marriage while discussing gay marriage, says it was joke

Sen. Rand Paul (R-Ky.) on Wednesday appeared to suggest a link between the Supreme Court's rulings on gay marriage and marriage between a human and a non-human, but later walked back that suggestion and said it was a joke.

"It is difficult, because if we have no laws on this, people will take it to one extension further  -- does it have to be humans?" Paul said Wednesday in an interview with Glenn Beck, after Beck suggested some unintended consequences of the rulings, including polygamy.
