50 Cent puts frosty spin on ALS Ice Bucket Challenge

The Ice Bucket Challenge took a frosty turn when rapper 50 Cent nominated rival Floyd Mayweather to a challenge that didn't involve a bucket of ice water or the ALS Foundation.

The hip hop artist called out the professional boxer saying, "This is a special ALS/ELS challenge for you Floyd. If you could read one full page of a 'Harry Potter' book ... I'll give $750,000 to whatever charitable organization you want to. F--- the bucket of ice, man."

According to the Daily News, 50 Cent may have been provoked by Mayweather's MLive.com interview in which he slighted the artist along with Nelly and T.I.

Mayweather has also been asked to complete the actual Ice Bucket Challenge by street magician Criss Angel.
