The perfume hoax is an urban legend about people approaching others claiming to sell a perfume and spraying them with ether or another chemical to knock the person out, allowing the "seller" to rob them.

Although the perfume hoax began in the United States, the tale has spread internationally. Emails describing the perfume hoax have been found circulating New Zealand, Ireland and the United Kingdom just to name a few. All of the relevant details stay the same, but specifics are given a local flare. Each time the perfume hoax is passed on, it is under the guise of a story that's happened to a friend of a friend.
