Floyd Mayweather finally admitted to knowing who Ronda Rousey is, but he also used the opportunity to fire back at her for a comment she made at the ESPY Awards last month.

Rousey beat out Mayweather to win the award for Fighter of the Year, and said at the time, "I wonder how Floyd feels being beaten by a woman for once," which was a clear reference to Mayweather's history of involvement in domestic violence incidents.

Mayweather was complementary of Rousey initially. But when he was reminded of her previous insult, he simply couldn't resist, and (of course) pulled the money card when delivering his response. 

"I've yet to see any MMA fighter, or other boxer, make over $300 million in 36 minutes," Mayweather said. "When she can do that, then call me."

Mayweather's nickname is "Money," and his brand is The Money Team. So the fact that cash continues to rule everything around him shouldn't come as too much of a surprise.
