There's a whole reason behind the limp without the limp House wouldn't be how he is...when he's angry at the world..etc. Without the limp the show would've gone no where.
The Limp is totally not authentic in reality. Dr. Gregory House, not Hughe Laurie, had a muscle problem on his leg or something years back. You have to watch previous episodes to get it, if you havent watched them.
It adds to him. Having something that makes him stand out makes you watch him closer than the others. He is a complete Asshole with a capital-A though, but still a bloody brilliant doctor.
I need to watch that more often. I spend too much time on Law and Order.
I think House got a really bad infection and they had to severe some important muscles of his leg and that's why he is limping now. If my memories are right...
I like the limp. It brings him down to earth - makes him real. It isn't easy to look at, but neither is some of the other gore they show on that program. I like how House is Sherlock Holmes with a limp. The limp puts the show in context and adds a little bit of pathos. It makes you believe that somewhere under his jerky persona, there is someone who is actually trying to prevent bad things (like what happeneded to him) from happening to others.
