This guy convinced his little sister the world was being taken over by zombies, after she had wisdom teeth surgery – and her hilarious reaction went viral!

The brother went to crazy lengths to convince his sister – who was still under the influence of a general anaesthetic – of a zombie apocalypse, he even recorded his own radio news bulletin and had the whole family jump in on the act.

At one point her other brother gets in on the action, asking her to choose between the family cat or dog.

“We can only take one pet, which pet? The cat or the dog?”

“The cat you idiot!!” she screams.

“Well what do we do with the dog?” the brother replies.

“He’s the worse, he’s already dying. Leave him and get the cat!” she says.

What a crack up! Check it out!
