Commentary talk:The Duh-Vinci Code

I noticed on the commentary for this episode when they discuss the Rube Goldberg machine about 14 minutes into the show, you can hear Maurice Lamarche talking in the background but you are unable to understand him possibly because of editing. Then John Dimaggio and Billy West tell him not to talk about that, and I always wondered what it was that he said. I don't know if anyone could possibly have the answer, but I thought it would be interesting to note.
