Pet Ball Implants

Artificial replacement testicles for dogs - available in three sizes, and three degrees of firmness – was one of the inventions that secured the spoof lg Nobel prize for fringe scientists this year. Another prized achievement was the calculation of pressure when Penguins poop.

The spoof prizes, awarded by the science humor magazine Annals of Improbable Research, were presented yesterday at a ceremony where the winners were asked to explain their work in a minute or less.

Testimonials by pet owners who are caring for their castrated dogs on the Neuticles site say: "He's a guy and I wanted him to remain looking like one." "Neuticles were the absolute least I could do."
