The Newport Centre snooker hall broke out into new dance craze 'Harlem Shake' ahead of the semi-final between Stephen Maguire and world number two Judd Trump at the Welsh Open.
The craze, which seems to have taken over from 'Gangnam Style', was performed by members of the crowd and announcer Rob Walker.
Following the dance, Maguire managed to see off his opponent 6-4 to book a place in the final.
