After cancelling his wildly popular comedy tour “Weapons of Self-Destruction” because of serious heart problems, Robin Williams is soon to be back on the circuit. And by all accounts, his over-the-top sense of humor is undiminished.

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!
