There was a man who spent his entire life looking for kulahs (leniencies) in all aspects of halacha (Jewish law) - whatever it was, he would search around until he found a rabbi who had a more lenient opinion he could rely on. After 120 years, he came up to Shamayim. Hashem looked at the man's life record and said, "Well, you certainly did everything I asked of you. Angels, please take this man straight to Gan Eden!" The angels escorted the ecstatic man straight into the gates of heaven and brought him into a small room. But when they arrived, all there was in the room was a dark, damp cell, a table, and one small candle! The man was shocked and quickly looked at the angels and asked in horror, "This is Heaven???" The angels looked at him and said "According to some opinions."
