BTW, there's a funny French film from way back in 1931 called Boudu Saved From Drowning. A well-to-do academic type man looks out the window of his fashionable riverside apartment and sees a homeless man drowning. He rescues him, and generously invites him to live with him for a while. The man's high society wife and friends are appalled, but the rich man is bored and finds the homeless man entertaining. The homeless man continues to act like a slob. Even so, the rich man insists on keeping him around, being socially committed to improving the life of one of society's less fortunate. But the homeless man eventually falls in the river (on purpose) and fakes a drowning so he can escape and go back to living on the streets again, which he prefers.
They ought to show that film on college campuses instead of An Inconvenient Truth or Bowling for Columbine.
Down and out in Beverly Hills?
I believe it was remade also in the late 50s early 60s. (IIRC)
