The cheeky monkeys at the London Zoo have been causing a bit of trouble lately.
The little buggers have been stealing sunglasses off of the heads of tourists passing through on sunny days!
Zoo officials say the animals love to see their reflection in the lenses, but have formulated a plan to prevent any more monkey business.
They plan on spraying the stolen sunglasses down with a bitter concoction which will hopefully turn the animal's taste for fashionable eyewear sour.
