A hilarious video has emerged online in which a monkey is seen whispering something to a man sitting next to it. The monkey first patted the man on the arm to attract his attention and then confided something apparently very important to him. The man returned the favour and whispered something into the monkey's ear and then showed the animal something on his smartphone. We can only guess what this enigmatic conversation was about, but it seems like there was a lot of understanding between the two.
