Major character is putting it pretty strongly. But I agree he's definitely dead.

Attempted, I'm pretty sure. He was in critical condition or something, and then we never heard of him again.

The Simpsons had an onion on its belt? It was the style at the time.

I, for one, would like the Simpsons to be put on trial in some small town, and have people show up to testify about every selfish thing they've ever done.
