Hundreds of people queue to be ‘cleansed’ by guinea pigs in bizarre ritual

Short form: a shaman rubbed a guinea pig on a large number of people to cure them of their ailments, and likely their overly-fat wallets. No information was given about how the guinea pig felt about it; looked disturbed to me, but maybe it was just happy to be the center of attention. Also no word about whether the critter had been cleaned of plague-fleas prior to this. And the author did not render an opinion on whether it would be good or bad if a bunch of people who buy into rampagingly stupid nonsensical superstitious quackery caught some horrible life-ending, gene pool winnowing disease.
