It's Mehmet Okur (originally from 6/28/05). I'm not sure, but I believe it's tonight's special guest Jon Glaser.
"Mamet Occur" is some awesome butchering work.
Isn't Jon Benjamin Memhet Okur?
If I'm not mistaken, he makes at least one other call to the show. He and Skag Winesack are among the callers that I wish would come back, if only for one night.
