Transcript for Ball-playing lookalikes
REPORTER: This is Brady Feigl, and this is Brady Feigl.
- I feel like Brady is not a very common name to begin with, but then Feigl on top of that.
REPORTER: But somehow, they're not the same Brady Feigl.
- We both wear glasses. You know, we both have red hair. And we like-- the fact that we both play baseball in-- at the professional level--
REPORTER: Not the same person, but perhaps, a real-life Parent Trap.
- We're like twins.
REPORTER: One half of this Brady Bunch, joining us to help make a double play.
- I'm the one from Maryland, and a little bit older.
REPORTER: Our Brady first found out about the other Brady when he was asked to autograph a game card.
- They're like, oh, can you sign it? I'm like, that's not me.
REPORTER: The doppelgangers paths almost crossing again in 2015, when they had the same elbow surgery from the same doctor.
- He had his a little bit before me. So when I showed up, they pulled his file. They're like, didn't we just do your right arm? And I was like, no.
REPORTER: Not the kind of place you want to pull a Hallie and Annie.
- I think we should switch places.
- I was like just-- just make sure you do the right arm, like, the correct arm, please.
REPORTER: Finally, after becoming an internet obsession, the lookalikes met up and took a DNA test to see if more than coincidence was at play.
- Pretty much found out that we're not related. But I've had-- I've had numerous people on like, Twitter, they're like, can you do this test? It goes back 16 generations. I'm like, OK.
REPORTER: But a bond there, nonetheless.
- Maybe one day we can be on the same team, and he can start a game and I can close one. And that'd be pretty cool to see-- to see across the ticker at the bottom. It's like, Feigl got the win, and Feigl got the save. That'd be-- that'd be-- that'd be pretty cool.
- An entire stadium of Feigls in the stand.
- Feigls everywhere. OK, a study came out five months ago that suggests that doppelgangers, like the Bradys, probably share DNA with one another, even if they're not related. And the lead researcher takes it one step further, saying, I think all of us, right now, have somebody that looks just like us, a double.
- We were just talking about this.
- I don't know.
- And you almost wore the same ties--
- I know.
- --so you could have been doppelgangers.
- [INTERPOSING VOICES]
- I just want someone to tell me I look like Andrew. You know?
- I won't believe this until they go on Maury.
- Not Maury.
- A lie detector test determined that was a lie. More news next.
