While in the paddock area with a horse called "Bell Boy," Bilko is making sarcastic comments to Henshaw and Rocco about that horse. They had received a tip from a new recruit, fresh off the farm in Kentucky - a kid who knows all about horses who told Bilko to bet this horse. "Hey," explains the recruit "Pvt. Carter," "he has good breeding. He's from the family of Native Dancer."
"Yeah," replies Bilko, "that explains the slow mambo he was just doing. How am I going to face my platoon when I've lost half their money on this horse?"
After Bilko finds out the horse is for sale for $100 and the kid discovers second later that the horse has a leg problem he could fix. "When he's cured, the horse could make thousands winning stakes races," says the new recruit. His greedy Bilko is hooked and buys the horse.
The problem is "how do we hide the horse from Colonel Hall?" Later, it also becomes, "How do we feed the horse, get blankets, medical supplies, etc?"
To make matters worse, there is going to be a surprise inspection by old "spit and polish," which has Col. Hall very concerned.
This was a fun episode with a couple of memorable scenes, such as the four guys in the platoon having to eat oats for four days and the Colonel being woken up each night at 4 a.m. hearing a horse race by his window.
