What was Wes Craven's Scream 4 cameo?

Okay so I just saw Scream 4, I was not looking for Wes Craven's cameo so of course I did not see it. I heard that it was really obvious to anyone who actually knew what he looked like. Now I'm curious as to who he was. So, anyone who saw it got any idea what his cameo was in the film?
