Get the YoY mug.
The ethereal being of all creation. YoY sees everything and quietly listens to the soundtrack of Thomas the Tank Engine. YoY looks like a train with a long human nose. YoY stands on two stick figure legs and has no arms. Some followers refer to YoY as the second coming. Those who choose not to believe in the great YoY will be subjected to eternal damnation in the fiery pits of Hell. YoY chooses to abandon institutionalized religion and rather seeks salvation from within. Join YoY on its quest for eternal domination of all that exits.
A quick search on Google Images will provide you with an illustration of YoY.
All praise YoY! Our founder, our love, our inspiration.
