Callum Wilson scored twice on his debut, and midfielder Marc Pugh after just 24 seconds, as Bournemouth routed Huddersfield.
Wilson, a £3m buy from hometown club Coventry, first barged Town’s Joel Lynch out of the way and coolly netted after 32 minutes.
Wilson’s second goal, from a Pugh cross, saw a weak close-range shot after 64 minutes squirm under Alex Smithies.
Between Wilson’s two strikes Yann Kermorgant had scored in what was already a miserable afternoon for Terriers fans.
Wilson joined the Cherries as a replacement for star striker Lewis Grabban, who was sold to Norwich in the summer.
His second goal prompted a walk-out by some home fans, who booed and chanted “you don’t know what you’re doing” at boss Mark Robins.
Wilson even fluffed the chance of a hat-trick when he missed a penalty after 76 minutes when Smithies brought him down but the keeper saved the spot-kick.
Pugh had struck before the season was one minute old, dispatching the ball past Smithies after Charlie Daniels and Matt Ritchie had combined on the right.
