Not many people know that Abe Simpson is a highly decorated veteran of the Second World War. Even fewer people know that he is the inventor of the toilet and the man who made cats and dogs hate one another. No one knows these things about Abe because no one listens to him. In fact, they usually leave the room when he starts to speak. Father of Homer Simpson, grandfather of Bart, Lisa, and Maggie, Abe, a.k.a. Grampa, lives in the Springfield Retirement Castle where he enjoys soft foods and company of his friends. Abe was lucky enough to briefly find success in his retirement as a writer for the award-winning Itchy & Scratchy cartoon series. That career came to an end when he publicly scolded the entire cartoon industry at an awards show. He has won no awards since then.
