Annie Golden returns as Margaret O'Keefe, the former postal trainee whom Cliff (John Ratzenberger) had fired for a rule infraction. Back in Boston, Margaret wants to renew her romantic relationship with Cliff -- a prospect that literally strikes him blind. Elsewhere at Cheers, Rebecca (Kirstie Alley) decides that it's time to put on a new face (and literally, at that). ~ Hal Erickson, Rovi
