After working side by side for weeks, two coworkers discovered that they are actually siblings brought together by a series of incredible circumstances.

Gary Nisbet and Randy Joubert, who share the same parents, were adopted and raised by separate families in neighboring Maine towns, never knowing the other one existed. They attended rival high schools, moved to the same town of Waldoboro, Maine, and both wound up working for the same company, Dow Furniture.

The two rode side by side in a delivery truck and slowly put the pieces together.

"Something clicked with me," Randy said. "So I got him up by the truck and said Gary, this is going to sound bizarre, but were you adopted?"

Gary, somewhat perplexed, confirmed that he was in fact adopted. After comparing some notes -- dates of birth, and finally birth parents names -- they stared at each other in disbelief.

"This is such a small world," Gary said.

Randy, the older brother, was the one who first had a hunch they may have been related.

"People are saying we look like brothers, and we go on deliveries together for the last month and a half and we keep getting it" Randy said. He had recently dug up some information about his adoption and discovered that he had a brother who was born on June 10, 1974 -- Gary's birthday.

For two weeks the two kept the news to themselves, but last week they shared their story withco-workers.

Owner Lisa Dow says she cried when one of the brothers told her, "I would have never found him if you didn't hire me to work here."

Gary and Randy are still in disbelief.

"I've been riding around with this guy for a month and a half and he's my full blooded brother," Randy said shaking his head.
