The Indian Parliament is no longer monkeying around.

After years of rhesus macaque monkeys menacing New Delhi's government buildings, the New Delhi Municipal Corporation has hired 40 men to impersonate the langur monkey, a larger species, to scare the rhesus monkeys away. The men will cry like the monkeys and threaten the cheeky trespassers.

"Various efforts are being made to tackle the monkey and dog menace inside and around the parliament house," India's Minister for Urban Development M Venkaiah Naidu told parliament on Thursday. "The measures include scaring the monkeys away by trained persons who disguise themselves as langurs."

The scarers, however, won't be dressing up as langurs.

"These men who are village performers and some of them have played monkeys on stage," PK Sharma, the chief health officer for the NDMC, told The Guardian. "So they mimic the sound of the langur and it scares the smaller, red-faced macaques away."
