What a great day...
1864: 3/5 of a person
2009: President of the United States
...and now for some snarkiness.
President Obama: You are the 44th President of the United States. You are not, however, the 44th person to take the presidential oath. You are the 43rd - Grover Cleveland makes you wrong.
Chief Justice Roberts: You had one job today. Stand up at your cue and say 35 words in order. No wonder Obama opposed your appointment.
