The tour was postponed after the comedian underwent major surgery at the Cleveland Clinic in March to replace his aortic valve, repair his mitral valve and treat an irregular heartbeat.

In a statement released by Mr. Williams’ publicists today, the comedian quipped: “This little break has given me more energy than ever. Plus it’s wonderful to have a cow valve … If you don’t mind the grazing, it’s quite invigorating.”

If laughter is the best medicine, Mr. Williams is one of the best docs around. Get well fast!
