I LOVE it! Maud just screams Asperger's (and I know Asperger's). Maud is Best Pony!
That whole family is somewhere on the spectrum, yeah; I'm fascinated by the different ways they've all found to cope with their own individual issues. I think Maud has a lot of potential as a Stephen Wright type of deadpan standup comedian, her sense of humor is solid as bedrock; her "...You're the most basic of jokes." line still has me rollin' in the aisles every time I hear it, it was just so perfect for the moment, and perfectly delivered.
