A video has gone viral after an American man convinced his sister a zombie outbreak was imminent.

The poor girl had not long had her wisdom teeth removed and was still slightly ropey from the anaesthetic.

Clearly her brother thought he would take full advantage of this and filmed the whole thing.

He went to great lengths to make it convincing and even brought his family into it via scary phone calls and radio announcements.

Clearly petrified at the situation, the girl was not impressed with the weapon she was given to defend herself saying “What is this going to do against anything, get me a knife!”.

Watch the hilarious video below.

Siblings can be so mean!
