What do you mean they are also prophets?

Far below, on the beach, were his friends
Half-naked bums
Partying in the sun
There were atheists
There were *** maniacs
The fat old Bumbo was a crazy bartender

I thought I was the only One. The Chosen One
I never knew they came in packs
All of them?
Even Bumbo is a prophet?
You mean to say you make me climb this eyrie-high
To tell I'm just one of them?
I'd rather not be a prophet
