Worcester posted their biggest-ever score in Europe as they ran in 13 tries against Spanish side Bizkaia Gernika in the Amlin Challenge Cup.
Worcester secured their bonus point in half an hour through Matt Kvesic, Blair Cowan, Ben Howard and Andy Short.
Short's second and Paul Hodgson rounded off an ill-tempered first half that saw both sides briefly reduced to 13 men.
George Porter, Hodgson's second, a Max Stelling hat-trick and Alex Grove extended the score after the break.
Joe Carlisle added 20 points from the tee and Federico Mazzochi managed to grab a second-half try for the hosts.
