From Dean Knox:
The banyan tree service is a story I have told many times.  I recall Bo
Blasingame giving the first one there and the echo of the lizard call
emanating from within the tree as he gave it.  I called it the F--- You Tree
as the sound was a definite high pitched F---Youoooooo and it certainly came
from the lizard that lived in a hollow of what is pictured.  I recall that
animal stuck his head out once when an audience was gathered. Bo was so
startled he definitely lost his train of thought when it came out (more
than once),  his audience laughed their butts off
