With the ALS Ice Bucket Challenge continuing to do the rounds amongst the biggest names in the celebrity and sporting world, Floyd Mayweather has been on the receiving end of a rather unique challenge of his own from non other than rapper 50 Cent - a man fast becoming the closest thing Mayweather has to a nemesis.

Calling out Mayweather

50 Cent, taking to Instagram on Thursday afternoon, laid out the rules as follows:

"Floyd will you except my ALS/ESL Challenge: I will donate $750k to a charity of your choice, If you can read a full page out of a Harry Potter book out loud without starting and stopping or f***ing up. lmao," wrote the rapper.

The challenge went down well on social media with '50 Cent', 'Floyd', and even 'Harry Potter' trending in the United States in the immediate aftermath.

But what was clearly another attempt from 50 Cent to get a rise out of Floyd Mayweather may have somewhat backfired - with the latter's own grammar diminishing its impact somewhat.

Accept is the word you were looking for Fiddy...

Developing Feud

Over the past several weeks 50 Cent has gone out of his way to mock Floyd Mayweather, with the rapper the latest in a long line of people to take exception to the boxer.

Only recently 50 Cent was riling Mayweather with comments (and photos) in reference to the undefeated boxer's former girlfriend posing alongside rapper Nelly.

Mayweather and 50 Cent are former friends but have in recent times been involved in a very public feud which continues to draw attention.

Mayweather himself took a not so subtle shot at 50 Cent and his rap fraternity in a recent interview and the music star's challenge Thursday ensures that there is no chance of things cooling off anytime soon.

Ice Bucket Challenge 

If Floyd Mayweather opts to answer the challenge set out before him he will join the ever growing list of sporting icons to have put themselves in an awkward position for charity in recent days.

Everyone from NFL Commissioner Roger Goodell and Lakers legend Kobe Bryant, to Chelsea manager Jose Mourinho and reigning NBA MVP Kevin Durant have answered the call in the name of the ALS cause.

And, with the help of the thousands of regular people who have taken part, all those involved have helped to raise millions upon millions of dollars with the simple challenge.

What Mayweather will do in response is anyone's guess but with 50 Cent putting $750,000 on the line lets hope the boxing great has something up his sleeve.
