Once in a generation it happens. Some enterprising soul hellbent on chaos decides to strip off all their clothing and streak at the Happiest Place on Earth. According to at least one X (formerly Twitter) user, this streaker shut down Its A Small World at Disneyland in Anaheim, CA.
Further down in the thread, Ashley Esqueda posted video from inside the ride, which had unfortunately stopped, meaning everyone on boats were stuck in the never-ending hellscape that is Small World.
Also, Esqueda says the man in question “jumped into the water.”
UPDATE
There is video of the man, who has not been identified by name, jumping into the water and climbing around some of the various scenes inside the ride.
