Anyone who knows, met or has ever worked with Larry David knows that his on-screen personality is very similar to his real personality.

I remember when I did a scene with him on Curb Your Enthusiasm, my friend Jeff Garlin showed up on the set early to warn me about Larry and not take anything personally. I was glad he did. While Larry wasn't the worst person I had ever worked with, he certainly wasn't pleasant. However, once the series aired, it was clear that he knew what he was doing.
