St. Peter At The Gate

Single Man: "I would like to come into heaven."
St. Peter: "Sorry, sir, you cannot come in."
Single Man: "Uhm. Are you sure?"
St. Peter: "Yes, sir, you cannot come in."
Single Man: "But I did my best."
St. Peter: "Sorry, sir, not good enough."
Single Man: "But I really tried."
St. Peter: "Not really."
Single Man: "What more could I have done? What did I not do?"
St. Peter: "You didn't go to the dances."
