I wonder if anybody gets the connection...
I'm still puzzling over the fridge...
Crystal is a company that makes (made?) refrigerators. I think they may have gone bankrupt or something because I can't seem to find anything relevant online. However, I know people who have Crystal refrigerators.
As for Pinky and the Brain, when the Animaniacs did their Star Wars spoof everybody kept mistaking Brain (R2D2) for kitchen appliances. And the closing credits song was "It's Pinky, it's Pinky and the Fridge Fridge Fridge Fridge".
EDIT: The internet totally rocks. I remember watching this as a teenager 15 years ago.
