Here is something Joe Biden said to Lindsey Graham recently: "I will rip your skin off for you, and I expect a thank-you note."
One of two things is happening here. Either Biden, aware of his unpopularity with Republicans, is offering to verbally attack Senator Graham in a particularly harsh manner in order to make him more appealing to conservative voters, or Biden is eyeing Graham for the human-skin suit he's making, and believes the South Carolina senator should be honored for the opportunity to literally be a part of history.
Wait, hold on ... okay, so, it's actually the first one. You're absolutely sick if you thought it was the skin-suit thing. Seriously, get help.
