But what if you were working with your sibling and didn’t even know it.
And then to make matters even more weird, what if you and your sibling were both A-list movie stars?
Well, that might be exactly what’s happening with Matthew McConaughey and Woody Harrelson, two very good friends that might be bothers.
CBS News reported that "In Greece a few years ago, we're sitting around talking about how close we are and our families," McConaughey said. "And my mom is there, and she says, 'Woody, I knew your dad'.. Everyone was aware of the ellipses that my mom left after 'knew.' It was a loaded K-N-E-W."
"We went on to unpack what this 'knew' meant and did some math and found out that his dad was on furlough at the same time that my mom and dad were in their second divorce," McConaughey continued. "Then there's possible receipts and places out in West Texas where there might have been a gathering, or a meeting, or a 'knew' moment."
A stunned Ripa asked McConaughey if the two have taken a DNA test to confirm any blood relation. McConaughey said they are "on the precipice" but that he is a bit more hesitant than Harrelson.
"It's a little harder for me, because he's asking me to take the chance to go, 'Wait a minute, you're telling me my dad may not be my dad of 53 years' and believe in it? I got a little more skin in the game."
McConaughey talked about his close friendship with Harrelson, saying that their kids often confuse them in photographs.
"My kids call him Uncle Woody. His kids call me Uncle Matthew etc. etc.," he said. "And you see pictures
of us and my family thinks a lot of pictures of him are me. His family thinks a lot of pictures of me are him."
Well, all they need to do is get a DNA test to find out… so what are they waiting for?
