Just a day after Floyd Mayweather Jr. threw a job at Manny Pacquiao, the Filipino champ and his supporters fired back at the Grand Rapids native as a meme humorously depicting Mayweather's never-ending excuses to face the eight-division champ becomes viral on several boxing forums and social networking sites.

Mayweather's Christmas Card aimed to ridicule Pacquiao's knockout loss at the hands of Juan Manuel Marquez a year ago has become an instant hit on Twitter, already garnering as much as 22,861 retweets on the microblogging site.

Money May, who is fresh from collecting more than $100 million this year after booking sensational wins against WBC Welterweight Champ Robert Guerrero and WBC Light Middleweight Saul Canelo Alvarez, apparently made of fun Pacman following reports that the Filipino champ and Top-Rank promoter Bob Arum has once again called him out to settle their differences in the ring once and for all.

However, Mayweather again ruled out of the possible showdown with the eight-time division world champ, saying a fight between them will never happen at all as long as Pacquiao is fighting under Arum and Top-Rank promotions.

"We all know the Pacquiao fight, at this particular time, will never happen, and the reason why the fight won't happen is because I will never do business with Bob Arum again in life, and Pacquiao is Bob Arum's fighter," Mayweather told FightHype.com.

"Bob Arum gives Pacquiao a date, whereas Floyd Mayweather gives Floyd Mayweather his own date. I will be fighting again in May and I will be fighting again in September," he added.

Pacquiao's Payback

Just 24 hours after Money May's Christmas Card became viral, Pacquiao allegedly responded by posting a Christmas card meme that shows Mayweather and his many excuses not to fight Pacquiao.

Though there's confirmation that Pacquiao indeed posted the meme as response to Mayweather's low-blow, the Filipino fighting congressman is still thanking Mayweather that he hasn't forgotten him at this time of the year.

"I'm thanking Floyd Mayweather that he has not forgotten me. I'm glad that he is still thinking of me," Pacquiao told the Philippine Inquirer.

Pacquiao added that he has no ill feeling towards Mayweather, who continuously fired insensitive comments to him.

"Christmas reminds us of God's greatest love for us. He teaches us to love even our enemies. So, I won't say anything that would hurt anybody," Pacquiao said.
