Boo, hiss. A homeowner was terrified to discover nearly 100 venomous snakes in a writhing black knot in his backyard — in a case experts have described as a “rare occurrence.” The trouble began last week when David Stein initially spotted a handful of the slithering creatures clustered together in his garden — leading the Australia man to immediately call in a specialized removal crew.

Living in Australia means you might have to accept coming across a snake or two on your property at some point. But one Sydney homeowner got more than he bargained for when a snake catcher unearthed 102 of the slithery reptiles hiding in his garden.
