May 13-19: Dallas’ second-most-famous moment, Super Mario is 64, Joe Piscopo goes Jersey, Peter Gabriel hits with a sledgehammer, Seinfeld commits stationary murder, Alec Baldwin is a prisoner, Bruce Willis goes over the hedge, MST3K’s gone for the first time, the American Dr. Who, Justice League fights to the end, and That ’70s Show hits the 1980s. All that and more from 30, 20, and 10 years ago.
