“We’re all sitting around in Greece one night talking and my mom out of nowhere in a little pause goes, ‘Oh, I knew your dad, Woody…,’” Matthew said.

“And we all went, ‘What was the ellipsis about? And what was the knew about?’ And she goes, ‘Just saying, we might have frequented the same similar place out in West Texas one time when he was on furlough.’”

“And we all went, ‘What? What, are you going to leave it there?’ ” he continued. “Now we gotta go do some DNA tests.”

As of now, neither Matthew nor Woody has taken a DNA test to discover whether they are actually brothers, however, perhaps one day the truth will come out!
