Tomacco
Wikisimpsons - The Simpsons Wiki
Tomacco is the produce made by Homer, when mixing Tobacco and Tomatoes after putting a plutonium rod in the ground near the tobacco and tomato plants. This was shown in E-I-E-I-D'oh. When Homer Simpson was selling it all the animals ate it.
Everyone hates the Tomacco but keeps eating it because of the nicotene in it from the tobacco. It looks like a tomato on the outside but inside it is the brown, flaky tobacco.
In the new high definition opening sequence, Maggie is on the store conveyor belt alongside a bottle of Tomacco Juice.
In The Simpsons Hit and run,a billboard can be seen over a Tomacco field.
