I have OCD (although it has actually got much better over the past couple of years) and I was not offended by the show but, then again, I'm quite hard to offend and many people might have a different view of things.
But I would be offended if people were laughing at his problem. It may seem funny to people but it can be tedious and irritating when you're inclined to do things like that obsessively.
It's me, Felix.
Name changes annoy everyone, I know.
