SLEDGE HAMMER! (1986-1988)
The Sledge Hammer! writers figured they weren’t getting renewed so they ended the season with the titular police nutjob blowing the city to kingdom come with a nuke. To the writers’ misfortune, Hammer was renewed, so they weaseled out by setting the second season five years prior to the first. Ultimately meaning that Sledge Hammer! vs. C.H.U.D. remains an unrealized dream. Get on this, prospective future millionaire!
