I would never put ketchup or mustard on a pizza. I've had a good "cheeseburger pizza" before, but it was just hamburger with mozzarella and cheddar cheese, plus onions and tomatoes.

"It's the factory, not the farming, that is the problem."
With you all the way! My paternal grandfather was a veterinarian. My father's maternal grandmother was a butcher. Both would be turning over in their graves at the way much of the meat we eat today is produced.

Half of me thinks of how burgers are pretty high in fat content anyway and to add more fat to them is courting a heart attack. The other half thinks how delicious this sounds.

It's cute, but beyond what you said, and possibly hiding the mouse from the cat, I can't see any practical use for it.
