Groaner

A traveler in the Himalayas came upon a great gathering of holy men and philosophers, representing all aspects of belief and including one aged guru reputed to have achieved Nirvana by subsisting entirely on a diet of asparagus.
The traveler was astonished when, in a sudden mountain shower, all of the participants in this conclave were drenched except the asparagus-eater.
"This is not incredible'" explained the guide. "Bliss is the awning of the sage of asparagus."
