Ami Felker, a spokeswoman for The Methodist Hospital, says Bush was in high spirits Thursday afternoon as she was moved to a patient room from the intensive care unit.
The former first lady was hospitalized Tuesday after experiencing abdominal pain.
Dr. Pat Reardon says surgeons closed a nearly 1.5-centimeter hole caused by an ulcer.
Reardon says the first thing Bush did after she woke up from the surgery was tell him a joke.
The 83-year-old former first lady is expected to remain in the hospital until next week.
