An Australian man was rushed to the hospital last week after a snake sneakily slithered into his car after he left the door open, according to police.

The unidentified 54-year-old man, who was with his dog, said he stopped at Back Creek Park, near Millmerran in Queensland, to swim on Friday night. He left his car door open, and the serpent found its way inside.

Upon his return to the car, the man was quickly bitten, 7 News reported. He told authorities he made a makeshift tourniquet with a ratchet strap and called 000, Australia's emergency phone number — but authorities apparently couldn't find him.
