Pupils at a Scottish school had to run for cover when it started raining worms during their PE lesson.
Teacher David Crichton was leading a group of pupils playing football on an astroturf pitch at Galashiels Academy when dozens of worms began plummeting from the sky.
The boys had to abandon their lesson as the earthworms fell during the bizarre incident, reports STV.
Mr Crichton, 26, said: "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."
Mr Crichton and his colleagues eventually found around 120 worms in total on the artificial football pitch and nearby tennis courts.
He added: "Everyone was having a laugh at me about it until they went out and saw for themselves. They were joking about it - and I said 'if you don't believe me go out and have a look'.
"Everyone thought I was mad. They came back in and looked shocked. The boys have certainly been talking all about it since then.
"I spoke with the science department here but none of them had any explanation for it. One of them thought maybe it was a freak weather thing. But it was such a clear, calm day."
