Every old show’s being rebooted these days; at some point, we’ll be living in a future in which “Designing Women” is once again sharing airwaves with “Murphy Brown”and a Roseanne-less Roseanne spinoff called “The Connors.” Ted Danson said that if they reboot “Cheers,” it will be without him.  He was on “Late Night with Seth Meyers” Tuesday to promote his latest show, “The Good Place.”
