Frictionless surface would hence support here only pure rolling.
Hence possible solution that he would have to toll along the smooth surface to get off.

							Spitting or coughing is the answer . As there is no friction we need to cough or sneeze which produces a suitable situation to get off. No other answer is possible

By splitting or coughing....due to frictionless surface there should be counter force which don't impact friction.
