Last week, we posted Curtis "50 Cent" Jackson's version of the ALS Ice Bucket Challenge, where he challenged champion boxer Floyd Mayweather, Jr.

His challenge was a bit different. He didn't want to see Mayweather dump water on his head. He challenged the Grand Rapids native to read a page from a Harry Potter book.

If he could successfully do that, 50 Cent would donate $750,000 to the charity of Mayweather's choice. It was basically a very elaborate way of calling Mayweather illiterate.

Well, we haven't heard from Mayweather yet, but that didn't stop 50 Cent from following up with a new challenge.

He doubled down this time, saying that Mayweather now just has to read a page from "The Cat in the Hat," since that might be more on his reading level. And Jimmy Kimmel has even gotten involved, saying that he'd provide the airtime for Mayweather!
