A whole lotta good it's dunham!

Sarcastic/amused remark regarding da lack of personal improvement, enlightenment, etc. dat da cantankerous ranting dat Peanut, Walter, Bubba J., and Achmed have displayed over da years has had on their puppeteer.

Walter always trumpets da advantages of being crabby and overly serious, and Ahmed rails at Jeff about da supposed hazards of associating with 'infidels", but a whole lotta good it's dunham!
