Both billionaires say they take care of their family's dirty plates and glasses every night.
In a 2014 interview with Business Insider CEO Henry Blodget, Bezos said that doing the dishes is a part of his daily routine.
"I do the dishes every night," said Bezos, who's currently worth almost $95 billion. "I'm pretty convinced it's the sexiest thing I do," he joked.
Gates, who is currently the world's second-richest man, not only does the dishes every night, he enjoys it.
