Katt Williams isn't all about stand-up comedy and getting arrested.
He has a charitable side too, he showed in a big way Sunday.
After a performance in Boston, he gave a wheelchair-bound woman in attendance $1,000 after learning that the fan badly needs a kidney transplant!
Williams' gesture took place after the comic's security team saw the woman crying in the crowd and found out the surprising reason why.
She said that they were "tears of joy" because it was the first time she had laughed since being told by her doctors that she needs a new kidney.
