QUICK TAKES - May 14, 2009

Comedian Robin Williams, recovering from heart surgery, will resume his “Weapons of Self-Destruction” stand-up tour in September, his representatives said Wednesday.

Williams, 57, had to postpone the tour in early March after complaining of shortness of breath. He had surgery that month at the Cleveland Clinic in Ohio to replace his aortic valve, repair his mitral valve and correct an irregular heartbeat. He got a transplanted cow heart valve.

“This little break has given me more energy than ever,” Williams said in a statement. “Plus it’s wonderful to have a cow valve. . . . If you don’t mind the grazing, it’s quite invigorating.”
