The man, Vincent Browning, led his 1,600-pound African Watusi right into Petco outside Houston as carefree as if he were walking a dog.
The animal was so huge it just barely cleared the sliding doors with its horns. The steer even knew how to enter and exit the sliding doors properly by ducking its head.
Once the steer got inside, the gentle giant was greeted with a warm welcome from employees and customers.
People could not believe it as Oliver the curious steer looked around the store.
Browning said he wanted to "call their bluff;” however, the joke was on him.
The video was posted to Oliver’s Facebook page this week and has since gone viral with over 1 million views.
