Who says Rihanna isn't charitable?
I mean, she found Johnny Depp for her fashion show, by scouting for people living in tents down in Skid Row.
So, a blind guy is sitting on a park bench with his seeing eye dog right beside him. Suddenly, his seeing eye dog cocks his leg and pisses all over the blind guy's leg. So the blind guy gives the dog a treat.
A man taking a walk saw the entire thing and said to the blind man, "That is the most charitable thing I’ve ever seen, your dog deliberately pissed on you and here you are giving him a dog biscuit." The blind man says, "Oh it’s not what you think, I’m just trying to find his head so I can kick him in the ass."
