That's the crazy lesson Maury Povich, host of "Maury," learned during the oddest paternity test his show has ever aired.
On one episode of his long-running talk show, a mother sought a paternity test in hopes of identifying a man as the father of her twins.
"When I ended up reading the result, he was the father of one twin, but not the other -- and it was the most dramatic moment of the DNA theme we have ever had on the show," Povich told AOL News.
"I didn't even know that was possible," he said, "but when there are fraternal twins, you could have two fathers."
In rare instances when twins are conceived by different fathers, it's called heteropaternal superfecundation, according to Discover Magazine.
It occurs when two or more of a woman's eggs are fertilized by different men within the same ovulation period.
It's so uncommon that only a few cases have been documented in medical records.
