Fishin' 4 Religion is a song by Arrested Development. The song is about looking for another religion because he is bored with the one he has now. In the song her talks about seeing a lady pray and ask the lord to let her cope and she prays and prays. He talks about does shouting make you a better person because you shout in church and different things like that.
I personally think that none of the things described in this song are what differentiates a religious person and a person who has no faith or beliefs. I dont go to church and dont scream and I barely ever pray, but that doesnt mean that I have no faith and dont have my beliefs. In my opinion, all the shouting is just an exaggeration.
