A Simpsons fan has created tomacco by cross-breeding tomatoes and tobacco:
"What we found was nicotine in the leaves". said scientist Ray Grimsbo. The plant grew off the tobacco roots and sucked up the nicotine, just like Tomacco on The Simpsons. The lab hasn't tested if the actual tomato has nicotine in it yet, but they say it probably does. "Generally in the fruit there is more material concentrated because that's what everything's going through to produce the fruit for the next generation. I would expect there would be more." And that would make the real life tomacco plant very poisonous. Rob Baur says he grew the tomacco plant just for fun, just to see if it would really work.
