A giant Guinea Pig who neeps daily for his fans, can be seen on your local "big guinea network" (check local listings for station). Can be seen every night at 11PM. Many believe it to be a product of heavy drug use, but they are wrong. The Big Guinea is a product of mental retardation.
Dude, did you see the Big Guinea neep 3 times last night?!
