Scott McClellan signs off with a sick gag:

"Finally, I want to thank each of you in this room and each of you in the White House press corps that aren't here today. Thank you for all you do to keep the American people informed. Thank you for all you do to hold those of us in elected office accountable for the decisions that are made. Keep after it. Keep up the good work. You are a terrific bunch of professionals, and it has been a real honor to serve with you all. Thank you."
