"I am on Desperate Housewives now and having a blast. The girls are fun to work with and the production is top notch. I am doing at least four episodes and maybe more. Look for me to show up the week before Thanksgiving and from there after for awhile. Good stuff, but I can't tell you anything about it. Sworn to secrecy!" Former Dukes of Hazzard star John Schneider is keeping quiet about his upcoming TV role.
