Yeah, why only garbeige?

Why not gargreen? Or garyellow. We have garage but not garheight or garweight. Do you measure garage in years or in garyears? I mean, everyone has ears, not just Gary. Maybe that's why there's no garyellow... What the heck is ellow anyways, Gary wouldn't ever have any of that! Not in his Garage, or his garbage, even if we all see it as garbeige.
