Joey Taylor's parents bought him a book on the history of U.S. Presidents, knowledge that he soaked right up.
In a video posted on YouTube, Joey's mom throws out random presidents and asks him who was president the year they were born and the year they died.
Joey also adds historical details on his own.
When Joey's mom asks him who was president in 1848, he spouts off what he knows.
"I think that was Polk. He almost won. He didn't win a second term. He died three months later. Polk died three months after he left office," Joey says in the YouTube video.
"And who won the second term?" Joey's mom asks.
"Zachary Taylor. But Martin Van Buren tried again but did not win," Joey says.
His parents think he has a photographic memory.
"He's been memorizing things that he finds interesting. Then it amazes us," says Joey's mom, Samantha Taylor.
