A spokesman says former New York City Mayor Ed Koch (KAHCH') is feeling "much better" and cracking jokes.

George Artz said Tuesday it's still not clear when Koch will go home. The former mayor was hospitalized Saturday night with fluid in his lungs and swollen ankles.

Artz says Koch has praised the chocolate milkshakes at NewYork-Presbyterian/Columbia hospital as delicious, but not worth the hospital stay.

The outspoken Democrat has also been known to serve up his opinions as a movie reviewer and a judge on "The People's Court."

Artz says the 88-year-old Koch has been told he'll have to limit his salt intake.
