"They may have turned this up, whether you had the Paula Jones case or not. But again maybe not, but again that's like if a frog had side pockets he'd probably wear a handgun"

This quote by Dan Rather is a humorous method of saying that particular occasions may have happened no matter other circumstances. He is recommending that even if the Paula Jones case had actually not occurred, something else might have happened that would have triggered the same result. He is also suggesting that it is unlikely that something would happen that would have been completely unanticipated. The frog example is utilized to highlight the unlikelihood of something unforeseen happening. He is saying that if a frog had pockets, it would be so not likely that it would be nearly difficult. This quote is a funny way of highlighting the improbability of something unanticipated taking place.
