This is someone's answer to the religious imagery in traditional Christianity(i.e. God as an old man with a beard, Christ as a well groomed hippie of the 1st century, angels as men and women with wings, etc. etc.)
Needless to say, early Christianity had no need for these icons because they knew they were dealing with spiritual beings and spiritual worlds where the forms could be anything imaginable.
There's no reason why present day Christianity has to be fixated on the dogma of the 4th century(i.e. "The Creeds of The Church") or the visions of Christian artists of the Middle Ages.
The "Flying Spaghetti Monster" simply perceives an alternate form and individuality for God similar to "George Burns" in "Oh God" and "Alanis Morissette" in "Dogma".
The God of Abraham, Moses and David doesn't have to conform to the reality and comfort levels of the Roman Catholic Church or any church at all for that matter.
That God has went outside of middle-of-the-road Christianity to show his sense of humor is a demonstration of his power and flexibility.
