Irvine's horse made a break about that time.
It may have been Irvine calling his horse an idiot.
I don't know Irvine.
Never meet him, but I know a gazillion catch drivers.
Here is how it often goes.
Colt makes a break and on the race track the driver calls it an "Idiot".
Driver tells the Owner/Trainer "Just a colt misstep. Pull up the overcheck abit and shorten the hopples a hole and next week this colt will win for fun".
Catch driver walks away thinking to himself "I hope I don't get stuck in to driving that Idiot next week".
