Alec Baldwin and Millard Fillmore
Everyone has a twin. This gallery proves it. Here you can see the Twitter Master's resemblance to our 13th president.
Justin Timberlake and Unknown Man
What's the Timberlake doppelgänger thinking about here? Probably some cool new dance step.
Leonardo DiCaprio and Unknown Woman
Imagine what "Titanic" would've been like if Leo's female twin was the one starring opposite Kate Winslet.
Charles Darwin and George Carlin
Carlin upset the status quo with seven words, but Darwin did it with one: evolution.
Maggie Gyllenhaal and Rose Wilder Lane
While Lane was probably proud of making it as a journalist, travel writer, novelist and political theorist, just think of how excited she'd be if she knew she'd one day kind of look like Jake Gyllenhaal's sister.
Young Albert Einstein and Shia LaBeouf
Here's a theory: History will remember only one of these two people.
Alexander Severus and Eminem
This may be the only time you'll ever see the names "Alexander Severus" and "Eminem" in the same sentence.
Ellen Degeneres and Henry David Thoreau
It's those eyes. Wow.
General MacArthur and Bruce Willis
Something tells me that the General would've been a huge fan of "Die Hard."
John Travolta and Unknown Man
Two pretty cool-looking dudes.
Nicolas Cage and Unknown Man
They should make a movie about this unknown man. We know who could play him.
Paul Revere and Jack Black
Both will go down in history as dudes with really loud voices.
Philip IV of Spain and Mark Zuckerberg
Oh, this reminds us: Please like and share this on Facebook.
Robert Pattinson and Unknown Man
Sorry, but the anonymous guy looks way cooler.
