10. Sal Romano
Showcase Episode: "The Hobo Code"
Sal probably tops the list of long-gone regulars fans are praying to see again in the finale. Lord, this man knew how to give a bitchy shrug. The debonair yet tragically closeted art director always had to hide his private heartache, but he impressed Joan with his cologne and Lois with his "ciao ciao." I hope Sal made it to the Seventies in one piece — he deserved it.
