50 Cent used the ALS Ice Bucket Challenge to troll his former friend, boxer Floyd "Money" Mayweather, with a contest of a different nature. Fuck a bucket of ice and $100: 50 will donate $750,000 to any charity if Mayweather can read an entire page of a Harry Potter book.

Out loud. "Without starting and stopping or fucking up. lmao."

50 sort of undermined his "ALS/ESL Challenge" by scrambling the acronyms in his Instagram video, but he's also been shot 9 times, so whatever.

In an interview with Mlive that ran today, Mayweather addressed his beefs with various rappers, including 50 and T.I., who he reportedly scuffled with at a Fatburger in Las Vegas earlier this year. (50 made fun of the champ for that one on Instagram at the time.)

"God has blessed me with an unbelievable talent, with fast feet, fast hands, unbelievable defense and a very, very sharp mind. So I'm thankful for that. Of course, hip-hop artists, they come and go. They come and go. But I'm still here," he said.

50 had an answer for that, too:

Hip-hop artists may come and go, but so did Mayweather's ex-fiancée, Shantel Jackson. She dumped him for Nelly, a fact that 50 has been rubbing in the champ's face for months.
