At the end of the show, Tom gets hypnotized over the phone by P.J. Cloth (?), who was supposed to be in the studio, but his car broke down. He puts Tom to sleep, and then can't get him to wake up. Tom snores quietly for the final seven minutes of the show.
I have this in an MP3 but haven't listened to the full show archive yet.
Who plays P.J. Cloth? His voice is close to Jon Glaser's voice, but not enough to say "that's him." It may be the only unidentified (as far as I know) full-appearance character on the show. Assuming it is a character - I can't find an hypnotists named PJ. He's at the least playing along.
