Many years ago when you were young, back in 2006, a wizened old man named John McCain made a joke that Congress' approval rating was so low, "we're down to paid staffers and blood relatives."

The joke was so funny, the wizened old man repeated it. He repeated it again and again, until his dentures popped out, until it made his gums bleed! He repeated it 27 times in five years. Here is his most recent deployment, two hours ago on Twitter. Here is a list of every time he made the joke. If you laugh all 27 times, Papa McCain will reward you with a butterscotch candy.
