"A typical day in the life of Grindie includes exciting activites such as: Eating cereal, playing video games, pixelling up some sprites/tiles for his master - The evil Mr. Freeze (Bisse) and watching horror movies.

Grindie is one of the biggest Nintendo fanboys you'll ever meet (or not, since he never ventures outside his bedroom) and can talk for hours about how great they are and how pasting Miyamoto's face onto Christina Aguilera's body can be so arousing."
