Very interesting, the snarky tone of this whole thread; you guys should be on Letterman or Bill Maher! There are several hypotheses as to why the fish was chosen. The most probable is that it is a reference to the scripture in which Jesus miraculuously feeds 5000 people with fish and bread (Matthew 14:15-21, Luke 9:12-17, and John 6:4-13). The ichthys also may relate to Jesus as a "fisher of men," or an acronym of the Greek letters ɥɶlt;= (Iota Chi Theta Upsilon Sigma) to the statement of Christian faith "?ɖ?V ɥɜɫɖɗ?V ɶ? lt;=??V ɗ?ɜ" (Ious Christos Theou Huios St: "Jesus Christ, Son of God, Savior").
