Too late. I believe that in france a downs syndrome kid sued their parents for giving birth. Not sure if it was thrown out or not though.
IIRC, the case was more that of a mother suing doctors (via leverage of the child) for missing or inaccurate pre birth diagnostics. I think the doctors lost.
But anyway, I think it's tough to come up with satyrical commentary these days. It just seems that the "real world" has seen something more stupid, more gross or plain and simple more ugly that the poor average 'comedian' can make fun of.
