Leaving your dog locked inside of a sweltering hot car is illegal and can be extremely hazardous for your dog's health. And yet, lots and lots of people still do it every day. So recently, a man in Las Vegas decided to confront a driver who had left his dog inside of a hot car while running some errands with his mother. And it went about as well as you would expect it to. The driver tried to write the guy off while helping his mother into the car and made several excuses as to why leaving the dog in the car for a short period of time was okay. But in the end, the Good Samaritan had the last word.

"You, sir," he said, "are an asshole."

Zing! Watch the guy confront the driver in the clip above. And please: DON'T LEAVE YOUR DOG LOCKED IN A HOT CAR! How many times do people have to hear this before they start to listen?
