Blame astrology, numerology or just coincidence—some people who share a birthdate have more in common than the day they were born. Witness the following 10 sets of birth twins.

1. Charles Darwin and Abraham Lincoln (February 12, 1809)

Two of the outstanding figures of the 19th century were both raised as Christians, though Darwin died an atheist and Lincoln was, by some accounts, an outspoken non-believer. Both had unimpressive school records, but taught themselves to rise to the peaks of their professions. Both embraced change and detested slavery. Darwin’s most important work, On the Origin of Species, was published in 1859 – one year before Lincoln was elected president. With these events, both would challenge the status quo – changing the world, and winning enemies for their efforts. (Darwin would be denounced; Lincoln would be assassinated.)

2. Jimmy Hoffa and James Pike (February 14, 1913)

Hoffa was a powerful and contentious unionist, alleged to have ties with organized crime. Pike was the contentious Episcopal bishop of California, alleged to have extramarital affairs. Both were known as champions of the underprivileged. Hoffa bargained for low-paid workers and campaigned for prison reform; Pike supported the civil rights movement. Hoffa was finally convicted of fraud and jury tampering in 1967, serving four years in prison; Pike was tried for heresy for his radical ideas, which resulted in the formal censure of his views. But most spookily of all: They both disappeared mysteriously. (Pike’s body was found a few days later; Hoffa was never seen again.) Neither of their demises were ever solved.

3. Marlon Brando and Doris Day (April 3, 1924)

The evil twin syndrome (though we’re not sure which was the evil one). At their peak in the 1950s, they were polar opposites. Brando played rebellious, tough guys who mumbled everything. Day played wholesome, virginal sweeties who sang beautifully. But they had a few things in common. Both of their careers were the result of a misspent youth (Brando took up acting after being thrown out of a military academy; Day was singing in clubs at 16.) Both had reputations for being “difficult.” Brando came to the movies as a famous actor, but proved he could sing (sort of) in Guys and Dolls. Day entered movies as a famous singer, but proved she could act in Storm Warning. Both became attached to important social causes (Brando to the plight of Native Americans; Day to animal rights).

4. President George W. Bush and Sylvester Stallone (July 6, 1946)

These two have more in common than you might realize. Their oratorical skills have been criticized, but at their peaks, both were immensely popular. Their secret: people love a war… provided they win. They each have a past that they would rather forget. In the early 1970s, Bush had a drinking problem and multiple arrests; Stallone (as a struggling actor) was debasing himself in a skin flick. Bush has a history of failed business ventures; Stallone has had his own corporate disasters, like Planet Hollywood, his ill-fated co-venture with two of Bush’s friends, Bruce Willis and Arnold Schwarzenegger. Stallone’s two most famous roles also seem perfect for Bush. Like Rocky, Bush was an underdog, who triumphed (in the 2000 presidential election) without actually outscoring his opponent; and like Rambo, he has been keen to settle old military scores. Of course, neither Bush nor Stallone are as popular as they used to be, proving that celebrity is fickle business, however you achieve it.

5. Jeanne-Claude Denat de Guillebon and Christo Javacheff (June 13, 1935)

Few birth twins have proven more compatible than these two artists, who have collaborated on many projects over the past 40 years, and have been happily married even longer. They are exponents of environmental installation art, famous for wrapping Berlin’s Reichstag and the Paris’s Pont Neuf Bridge in plastic, as well as such public artworks as Running Fence, a 24-mile-long curtain in California, and The Gates in New York City’s Central Park.

6. Princess Diana and Carl Lewis (July 1, 1961)

They were among the biggest celebrities of the 1980s, winning overnight fame early in the decade – despite unlikely beginnings. As a child, years before becoming the world’s most photographed person, Diana was notoriously shy; Lewis, years before winning nine Olympic gold medals, was a “runt.” (Strangely, Diana showed more athletic prowess than Lewis at school, excelling in several sports.) Both became renowned for their charity work. After Princess Diana’s death in 1997, “King Carl” wrote a tribute to her: “She will be missed by the many that she touched. And our birthday will never be as bright.”

7. Albert Finney and Glenda Jackson (May 9, 1936)

Royal Academy of Dramatic Arts graduates? Check. Made their film debuts in early-1960s British “kitchen sink” dramas? Check. Became major stars in raunchy, Oscar-winning adaptations of classic British novels? Check. Turned down several film roles throughout their careers to focus on the theatre? Che-e-eck. Hey, these twins could almost be the same person! In fact, have you ever wondered why you’ve never seen them in the same film together?

8. Meryl Streep and Lindsay Wagner (June 22, 1949)

The super-woman of American stage and screen… and the star of The Bionic Woman on TV! How could that possibly be mere coincidence?

9. Meredith Baxter and Michael Gross (June 22, 1947)

Though these actors are best-known for playing a happily married couple in the classic 1980s sitcom Family Ties, they were actually (birth) twins. They’re not the only twins who have worked together in television and the movies, of course. Oliver Stone directed Tommy Lee Jones twice, while Quincy Jones wrote music for The Italian Job (1969), starring his birth twin Michael Caine.

10. Andre Agassi and Uma Thurman (April 29, 1970)

One moment – like 1994 – you’re riding high and everyone thinks you’re sexy. A few years later, you’re a has-been, ranked 141st in the world (or making appalling movies like Batman and Robin), but at least you’re married to a former teen star like Brooke Shields (or Ethan Hawke). A few years later – like 2003 – you have broken up with your ex-teen-star spouse, but at least you’re back in form. You’re number one in the rankings (or high in the box office), decimating (or slicing to bits) your opponents in court (or in the Kill Bill movies). Oh, and everyone still thinks you’re sexy.
