Hulk, the Viral Pit Bull Star, Wows New York City

— -- Not since Michael Keaton ran through Times Square in his underwear in the film "Birdman" has something created this kind of stir.

This distraction's name was Hulk, an 18-month-old, 175-pound Pit Bull who hails from Maine.

Hulk became an Internet sensation when his owners, Marlon and Lisa Grannan, posted videos on YouTube.

The enormous dog's best friend is the couple's 3-year-old son, Jordan.

Jordan was actually riding Hulk as "Good Morning America"'s Sara Haines took the dog on a walk through Times Square.

Rather than being scared by the imposing-looking dog, people flocked to him -- eager to touch and ask questions about the animal.

"GMA" decided to give the celebrity canine a little break with a spa day, where he was able to make friends with other dogs.

He got his teeth polished and his coat brushed. He even had a reservation at a hotel, getting treats, water and a nap.

Asked why pit bulls have such a bad reputation, Marlon Grannon said that it was often due to the owner.

"A dog is only as good as the owner," Grannon said.
