|No, this isn't a jellybean. Instead, it's an invention for Gregg Miller to allow neutered dogs to feel complete.
Yup, Gregg mortaged his home to produce his invention: prosthetic testicles for neutered dogs called "neuticles". These neuticles come in different sizes, shapes, weights, and degree of firmness. Link
Miller's strange invention now has also won him the dubious yet strangely coveted Ig Nobel prize, a spoof on the Nobel prize and is awarded for odd scientific accomplishments.
Other Ig Nobel prizes include an experiment to see whether people can swim faster or slower in syrup than in water, experiment to monitor brain activity of locusts while they watch Star Wars, and more. Link
