The folks at Circuit City apparently lack a sense of humor. Corporate headquarters has issued a decree telling store managers to "destroy all copies" of the latest issue of Mad Magazine.

Issue #492 pokes fun at the electronics retailer with a 4-page spoof of their weekly ads. Consumerist.com got the scoop from an anonymous tipster, who also forwarded a copy of the corporate e-mail.

Check out the one-page preview of the Circuit City spoof. To view the other four pages you'll need to purchase a copy of the magazine.
