You read, right: HARLEY LOVING BIKERS.

Bill Stump Jr., the twins' father, fashioned a kid-friendly motorcycle for the twins using a mini Harley Davidson.

Bill said he and his wife, Amber, wanted to do something special this year.

It might be the last time they get to pick the costumes for the twins, who are now 3 years old and therefore opinionated.

Liam is really into superheroes. Adelynn loves princesses.

As for their opinion about this year's costume?

"They love the motorcycle," Bill said. "As soon as they get out the car, they want to jump on the motorcycle."

The Stumps were Internet hits last year without even trying.

After nearly breaking the Internet last year with their adorable old people costumes, Bellbrook twins Liam and Adelynn Stump are back this Halloween season and this time they are bikers. (Photo courtesy of Bill and Amber Stump).

A picture of the then 2-year-old twins dressed as an elderly couple for Halloween went viral, reaching more than 60 million people and earning more than 1.4 million likes and 770,000 shares on Facebook.

Bill Stump said the biggest deal was when the photo was included in a Pizza Hut YouTube video "How to Win at Halloween."
