Real citation: "Not that I haven't done dumb things myself. I have. And intend to keep on doing some of them. But the Current Occupant has slept through his own presidency. He has no idea what went wrong. He knows less about governance than a cat knows about a can opener. He cut taxes during a costly war and made serious debtors of our grandchildren and he has ignored the future as if it doesn't exist. He is now about as popular as wet socks and deservedly so. And here were the people who spawned him and we got along pretty well."

Made-up citation: "In my world, pea soup and Star Trek: The Next Generation and Jimmy Fallon are as popular as wet socks and ever shall be. Then again, my dog thinks wet socks are a nummy marriage of cookie and pork chop and heaven. That must be why he rarely uses this expression."
