Teacher kisses pig as reward to pupils who stopped littering

Pupils in China were rewarded for not dropping litter by watching their teacher kiss a 20kg pig in front of the whole school.

Hong Yaoming, deputy head of Xianning Experimental Primary School in the central Hubei province, had made a pact with his pupils in March, promising that if they stopped littering then he would lock lips with a pig.

The students had discarded their habit within a month.
