Pizza Tree!!

Lisa: How did you even grow this?
Bart: Guess I just know more about genetics than you do Lis.
Skinner: Don't be so concerned how it happened, Lisa, just be glad that it happened. Now we can have pizza from the comfort of our backyard instead of driving to the store; well done Bart, first prize!!

Pizza tree!! I WANT ONE.... or eight haha I figured it might work like a tomato plant? Starting out as a bulb of crust, adding a layer of cheese, and when the pepperonis appear, it's ripe to pick! And it even grows its own lettuce lol
Ignore the forgotten colored sleeve of bart there didn't notice that till right now hehe
