Who is Ben?
Ah, yes, and what an excellent question that was, Mr. Happy. You see, Ben's not quite a mop, and he's not quite a puppet. . . . . . . soooooooo, in answer to your question, I dont know.

Why does Bens head look and smell funny?
Well, Mr. Happy, Ben lived a deprived childhood, and he is foreign to modern technology such as shampoo and brushes. In ancient times, there was a name for these types of people----------Hippies.
