(DAILYMAIL) — An Illinois middle school has broken the Guinness Book of World Records for having the most sets of twins in a single grade – two dozen of them.

Twin boys Luke and Ryan Novosel, both 11, discovered the fact when they began counting up all the other twins in their Highcrest Middle School directory, in Wilmette, Ill. while trying to find a way into the reference book.

‘We were absolutely shocked,’ said their mother, Nancy Fendley. And it wouldn’t just brush past the current record of 16. ‘It’s blowing it away,’ she said.
