Translation, please...

This morning, after driving into town, Garrett kept telling me about a corn vet that he had seen.  Since we had driven right by the vet's office, I thought he was talking about the corn field by the vet's office or something...

Later, we were in a nearby town - they were have a car show this weekend - a special kind of car show - and he kept calling out - there is another corn vet - look at that corn vet - oh! there is a yellow one - and that corn vet has it's top down... Yep - a corn vet is actually a Corvette!
