Larry Collmus is a horse racing announcer at Monmouth Park in Oceanport, New Jersey. In 2010, he provided a running commentary to a race that included horses named Mywifeknowsevrything and Thewifedoesntknow. The result was a denial-filled marital argument in the form of a horse race.
The Telegraph (auto-start video) informs us that Mywifeknowsevrything was trained by a woman and Thewifedoesntknow was trained by a man.
My advice: just apologize anyway and bet on another horse.
