From the chuckle department:
With Comcast High Speed Internet with PowerBoost, you’ll be able to get maximum enjoyment of the FairTax Internet Seminar without the headaches of dial-up or slower DSL. Call 404-COMCAST to get Comcast High-Speed Internet for just $19.95 per month for six months.
With Comcast’s recent problems with blocking clients’ Internet access, the choice of phone numbers is either unfortunate, hilarious, or meaningless, depending on whether you’re at Comcast, suffering from Comcast, or simply unaware of HTTP.
