Aw, c-mon, now. That was a rather obvious fabrication. As someone said earlier, Eric Clapton was always "God" but, if you really wish to be profane about Dylan, some regarded him as the new "Messiah". Maybe they still do.
And if you wish a graffito about Dylan, there was one in 1963 that was mentioned in a magazine around that time and, a few years later, a photo of it, taken by the late David Gahr, was published in a book. The graffito read: "Bob Dylan doesn't know his ethnic musicology". Maybe it's a bit high flown for the way this thread has developed but that was slightly funny and deeply ironic.
