This joke is a great "insert name here" one, so I just picked someone I like to make fun of!

Thomas Jefferson dies and goes to the gates of heaven, and notices that there are clocks with names on them everywhere. He asks Peter what they are for, and he says that there is a clock for everyone and the clocks move whenever that person is masturbating. He looks at his clock and sees that it is well past 8 o'clock, and blushes, and then notices that Alexander Hamilton's clock is missing. He says "Hey, Peter, where's Hamilton's clock?" "Oh that." Peter said,"We keep that in the office and use it as a fan."
