A PE class at Galashiels Academy, Scotland had to run for cover as it started raining worms.
The teacher and pupils were out playing football when they had to quickly abandon their lesson when worms fell out of the cloudless sky.
The teacher, 26 year old David Crichton said: “We went out to one of our outdoor areas – an all-weather Astroturf pitch.
“We were out playing football and had just done our warm-up and were about to start the next part of the lesson.
“We started hearing this wee thudding noise on the ground.
“There were about 20 worms already on the ground at this point. Then they just kept coming down.
“The kids were laughing but some were covering their heads and others were running for cover for a while.
“They just scattered to get out of the way.”
Following the incident, teachers went out to the football pitch and nearby tennis courts and picked up more than 120 of the worms.
“I spoke with the science department here but none of them had any explanation for it,” Mr Crichton said.
“One of them thought maybe it was a freak weather thing.
“But it was such a clear, calm day.”
Kenny McKay, headteacher at Galashiels Academy, said: “The event does coincide with a significant change in the weather in recent days and so could be the result of an unusual meteorological event.
“The students and staff of Galashiels Academy are rightly proud of their school for many reasons, including its record in sport and its beautiful environs.
“However, we never thought we’d be famous for such a strange event.”
“None of the students were hurt, although they did find the experience quite bizarre.
“None of them will ever forget the day at school when worms fell out of the sky.”
Weird rain is not that rare. There have been reports of falling frogs, fish and even snakes before.
Events involving worms were also recorded in 1872 in Somerville, Massachusetts, in 1877 in Christiana, Norway, and in 1924 in Halmstad, Sweden.
Be careful what falls from the sky!
