An anonymous man in Brisbane, Australia, shut down an entire police station after bringing in two birthday cards he had received. He thought they were filled with anthrax; it was actually cocaine.

Who knows why this happened—maybe his grandma thought this would be a great way to cheer him up on his birthday, since drugs in Australia are so terrible and expensive, or a dealer out there was testing out some sort of sample sale. But the man, terrified, brought the cards into Boondall Police Station, thinking it was filled with a deadly powder.

The station was subsequently shut down as officers brought out the yellow hazmat suits and the do-not-cross tape to set up about a 50-yard exclusion zone while they identified the powder. After a dip-test, ABC reports, forensics officers found that the powder wasn’t actually anthrax, but a little birthday treat sent from an address in the UK.
