Pandit Surinder Sharma, a famous Indian tantrick (magician) was on a televised panel discussion when he claimed he could kill any man with black magic in under three minutes. Fellow panelist, Sanal Edamaruku, the president of Rationalist International, challenged the tantrick to kill him right then and there. Hilarity ensued as Sharma chanted the death mantra, and, when that failed, waved a knife and sprinkled water on him, as Edamarku laughed the entire time.Link (Thanks, Kim!)
After two hours of this, the show's anchor pronounced the attempt a failure. The tantrick said he must be under the protection of a very powerful god, to which Edmarku replied "I am an atheist". The tantrick claimed nobody could stand up to his extra-special death spell, but that could only be performed at night. The TV station promptly arranged another trial at night, with predictable results.
