Loro Parque is a zoo in the Canary Islands. And they were running a drill this week where a 35-year-old employee dressed up in a gorilla suit, so the staff could practice how they'd handle a loose gorilla.
Unfortunately, someone forgot to tell one of the veterinarians on staff. Because he saw the guy in the gorilla suit . . . thought he was an ACTUAL gorilla on the loose . . . and SHOT HIM with a tranquilizer dart.
That dart had enough tranquilizer in it to take down a 400-POUND gorilla. The guy in the gorilla suit was taken to the hospital, where he's still in serious condition.
