In episode FABF07 of The Simpsons, "Milhouse Doesn't Live Here Anymore," Homer takes to begging on the street to raise extra money. He learns that there are six types of beggars. I remember, for obvious reasons, religious zealots was one type, but I can't remember the other five. I haven't been able to find them listed anywhere yet, so I'm wondering if there are any Homerphiles out there who might remember.
For many years I never watched The Simpsons as I was preoccupied, but I've since discovered its genius. It's full of little gems like that list of beggars and other brilliant commentary on a wide range of human behviour. It's one of the few things on tv that makes me laugh. Southpark is another that I'm just discovering.
