One of the most amazing things about "Dallas," which airs its final episode tonight at 8 p.m. on Ch. 5 (story on C1), is simply its longevity.

When the show premiered on April 2, 1978, Jimmy Carter was president of the United State, Calvin Rampton was governor of Utah, Ronald Reagan was just the former governor of California and George Bush, like J.R. Ewing, was working in the Texas oil business.On a more personal level, on April 2, 1978, your local television editor was a 17-year-old high school senior, about a month and a half away from graduation. (He's now 31, a high school and college graduate, and married with three children. And, with the help of reruns, he's seen every episode of "Dallas.")

Literally hundreds of television series have come and gone in the 13 years since "Dallas" premiered. If you were to watch one episode a day, it would take you almost a year to get through all 356 installments.

To help you recall some of the events involving the Ewings and the Barnes over the years, here's a quiz and a list of all those cliffhangers.
