No I don't think he overstepped the mark, he wasn't making fun of Harvey, he was making fun of Katie Price and Andy Read: the joke was supposed to demonstrate what selfish people they are. That is to say, he's making fun of Katie Price and other celebrities who use their disabled children for attention and publicity, I have seen countless magazine covers with Katie Price posing with Harvey on the front, with captions such as "I love Harvey no matter what" or "the pain of discovering my son's disabilities", and no she is not doing it to raise awareness for disabled people, it's purely for attention and to raise her profile.
I find it is not too different from the Movie Tropic Thunder, when there was uproar over the Simple Jack character; Ben Stiller wasn't making fun of the mentally disabled, he was taking a swipe at actors who play disabled characters to further their career.
Many people struggle to take care of their disabled loved ones who really do need help, especially now that the government has cut their carer's allowance; these are the issues we need to be talking about, not celebrities and their self-indulgence in seeking praise for fulfilling basic obligations with vastly more resources than most families.
