Rob Baur of Lake Oswego, Oregon, dreamed of bringing to life his favorite The Simpsons episode, one from 1999 in which Homer grows "tomacco," a combination tomato-tobacco plant. Even though it tastes foul and has a brown, gooey center, the entire town becomes addicted to the fruit after one bite, and Homer gets rich.

Baur grafted a tomato plant onto tobacco roots, and voilà, he had a real, live tomacco plant. The two plants can successfully become one because they come from the same plant family, which also includes eggplant and the deadly nightshade.
