50 Cent was apparently doing the ALS Ice Bucket Challenge, except he didn't, at all. Instead he threw a bucket of water off his deck and challenged Floyd Mayweather to something a little more ... wizardly.

The rapper has pledged to donate $750,000 to Mayweather's charity of choice, if the boxer can recite an entire page from a Harry Potter book without making a mistake. He's calling it an "ELS challenge," taking a jab at the boxer's language skills. It's a bold move by 50; now we'll see if Floyd knows his uppercuts from Hufflepuffs.
