| Tyrone Simpson
| Character Information
Tyrone Simpson, known better as Uncle Tyrone, is a cynical elderly Simpson relative who lives in Dayton, Ohio.
Judging from his age and appearance, as well as the fact that various members of the Simpson family (including Dr. Simpson) attended his birthday party, he is most likely Grampa Simpson's brother, making him a great-uncle to the Simpson family.
The family intends to visit him during his birthday.
According to Lisa, Uncle Tyrone is bitter and depressed; when the Simpsons were singing "Happy Birthday" to him, he said "Why won't I die?".
