Overconfident dudes, be humbled.
Some people apparently don't understand just how unbelievably good Serena Williams is on the tennis court.
Why they don't understand this is unclear. She holds more open era Grand Slam titles than any other tennis player, male or female. She's set Olympic records, ranking records, age records, prize money earnings records—the woman is a record-breaking machine. (Fun fact: Williams is the highest paid female athlete of all time, having earned $86 million in prize money during her career. The next highest is Maria Sharipova, with $38 million in prize money. If that's not total dominance, I don't know what is.)
Her list of tennis championships is a mile long. You don't even have to follow tennis to know that Serena Williams is a freaking powerhouse of a tennis player, not to mention one of the greatest athletes of all time.
And yet, there are dudes who believe they could take her on.
