It may be difficult to convince some guys of this but, let's be honest, they need to realize that their experiences warming the bench for some DIII school during their college days won't cut it against seasoned pros like Candace Parker or Swin Cash. And if you really think you can take the court against a beast like Serena Williams, then you are flat-out crazy. That woman will eat you alive, and then take down her next challenger for seconds. Sure, most women in the WNBA can't dunk, and the women's tennis game is a bit of a mess compared the Big Four-era dominance of the men's side, but in one week these ladies still put in more hours at their respective sport than what you do in a year. Good luck holding your own against them. You'd need it.
Of course I could beat [insert famous female athlete] at their respective sport.
