There's a movie I watched a while ago. It's a satirical anthology film about America. One story involves a man and his dwarf friend thinking some guy his wife is seeing is a terrorist (I'm a little hazy on this one). One story is about an apparent homeless guy and his kid (or it might have been niece). She runs away and he tries to find her, receiving help from a woman. The one I remember the most is an upper class white family. The father in the family realized they don't know any black people. So he goes about trying to rectify the situation. I've tried googling it but I'm getting hazy on the details. I remember the back of the cover art had the dwarf with a gun hiding behind a chair.

I found it- Anywhere USA
