A priest, a minister and a guru sat discussing the best positions for prayer, while a telephone repairman worked nearby. 

"Kneeling is definitely the best way to pray," the priest said. 

"No," said the minister. "I get the best results standing with my hands outstretched to Heaven." 

"You're both wrong," the guru said. "The most effective prayer position is lying down on the floor."

The repairman could contain himself no longer. "Hey, fellas," he interrupted. "The best prayin' I ever did was when I was hangin' upside down from a telephone pole."
