Former Mayor Ed Koch was released from the hospital Friday after being treated for anemia.
Koch was in good spirits at a press conference Friday at New York Presbyterian Hospital, anxious to get back to work and even referencing his trademark catchphrase.
"How am I doing is the question, right?" he asked.
Koch was admitted to the hospital Tuesday after experiencing symptoms of anemia, a result of blood loss from recent dental work.
He was slated to be a super delegate at the Democratic National Convention and began feeling sick while in North Carolina. He took the first flight back to New York and came straight to the hospital Tuesday.
Koch's longtime doctor, Joseph Tenenbaum, said he was treated with a series of transfusions and his medications have been adjusted.
