Get the shitfinity mug.
The actual name of Comcast's television, internet, and telephone service. The beloved cable company, widely respected for its honesty and top-notch customer service, was just trying to give its product an accurate name. However, customer complaints about the obscenity soon forced them to censor the name to "xfinity". Sometimes stylized as SHITFINITY®.
After his bill nearly doubled, Dave spent over an hour on hold determined to cancel his Comcast SHITFINITY®, but once the service rep. finally answered she simply refused to let him cancel it.
