And my 3rd pick is a show that was gone too soon, then revived, then gone too soon, then revived again. And now it has 10+ seasons, which is a thin category for me.
It's a sci-fi and a sitcom and a pre-1999 and a wild card, so it hits 5 categories, but I'm taking it in the
10+ seasons category
It's #3 rated episode is from season 10, where Professor Farnsworth invents a machine that can take a person back 10 seconds in time. You can see Fry holding that machine in the image below.
