Rocker Ozzy Osbourne has helped set a new world record by leading baseball fans in the longest and loudest scream, ever.
The record bid took place at Dodgers Stadium in LA during a match between the Dodgers and LA Angels, with Ozzy taking to the field at half time.
Ozzy - dubbed the Prince of Darkness - stood in the centre of the field and waves his arms to encourages fans to scream the word 'scream' for over a minute.
Adjudicators from the Guinness Book Of Records were on hand to measure the volume and longevity of the scream, which they confirmed as a new record.
In odd news, many fans said they were not aware of the Thinkcure event and were just screaming because they had seen Sharon Osbourne.
