Who is this God Person Anyway? is the third installment in a trilogy written by Oolon Colluphid. The other books in the trilogy are Where God Went Wrong and Some More of God's Greatest Mistakes. Colluphid continued his theme with Well That About Wraps It Up For God (which centres its argument upon the babel fish). Colluphid's 'philosophical blockbusters' are less controversial than that wholly remarkable book, The Hitchhiker's Guide To The Galaxy.
