Larry Collmus had noticed "Mywifenosevrything" and "Thewifedoesntknow" on the card for Sunday's seventh race at Monmouth Park in Oceanport but he says he didn't envision the outcome.
But when the horses were both in the hunt near the end, Collmus says he had a sense of what was coming.
Collmus kept up the call as the two dueled down the stretch, deftly flicking between the tongue-twisting names. His only thought: "Don't mess it up."
At the finish he exclaimed: "Mywifenosevrything more than Thewifedoesntknow. Whew!"
Video of the call has gone viral on YouTube.
Mywifenosevrything is trained by a woman, while a man trains Thewifedoesntknow.
