Gerard Depardieu reportedly urinated on an Air France plane in front of other passengers after flight attendants told him he could not use the restroom. The incident occurred Tuesday, after the “Green Card” star and revered French actor was asked to hold it for 15 minutes, just until the plane was in flight. Apparently that was not possible, so he unzipped and relieved himself right there on the carpet, causing the plane to return to the gate and be delayed for two hours so the crew could clean up what Depardieu did. He must have been super-popular once everyone reboarded. (New York Post)
