A pair of duelling horses left an announcer at a US racecourse sounding more like a confused husband.

Larry Collmus was left with the unenviable task of commenting on a race with horses called Mywifenosevrything and Thewifedoesntknow on the card for Sunday's seventh race at Monmouth Park in Oceanport.

When the horses were both in the hunt near the end, Collmus had to keep his concentration.

Collmus kept up the call as the two duelled down the stretch, deftly flicking between the tongue-twisting names.

At the finish he exclaimed: "Mywifenosevrything more than Thewifedoesntknow. Whew!"

Mywifenosevrything is trained by a woman, while a man trains Thewifedoesntknow.
