9. … a brief funny story… Aliso Viejo, California: After visiting an official-looking prankster website describing dihydrogen monoxide as an odorless, tasteless chemical that can be deadly if accidentally inhaled, city officials were scheduled to vote on a proposed law to ban foam containers from city-sponsored events because this “dangerous chemical” is used in Styrofoam's production. The measure was pulled from their agenda after the embarrassing realization that dihydrogen monoxide is none other than H2O.
