A priest, a doctor and a fresh engineer die and go the heavens gate

A priest, a doctor and a fresh engineer die and go the heavens gate, they hear gods voice and it says " My sons i am really very sorry but the heaven is full and i can accommodate only one of u. so to choose the rightful person one by one tell me what u have done in ur lifetime." The priest goes up first and says " well god i am a priest i am ur humble servent and have spent all my life working to spread ur message." The doctor goes up next and says " well i am a doctor and i have helped thousands of people recover from there illnesses and saved countless lives." The engineer goes up and says " well I worked as a s/w engineer and...." before the engineer could say any further the heaven's gate opened and god came out with tears in his eyes and said to the engineer "Say no more my son come with me b'coz u have already been through hell."
