Apple CEO Tim Cook joked that a 17th-century painting shows someone holding an iPhone.
Cook made the comment at a conference in Amsterdam, when a former commissioner gave him the perfect setup.
"Do you happen to know, Tim, where and when the iPhone was invented?" Neelie Kroes asked.
"You know, I thought I knew until last night" he said.
His joking response referenced a painting the pair saw the night before.
"I was so shocked there was an iPhone in one of the paintings," he said.
The art, called "Man Handing a Letter to a Woman,” was painted by Pieter de Hooch in 1670.
