Season eight of Cheers ended with Sam (Ted Danson) and Rebecca (Kirstie Alley) on the sofa in his office, poised to consummate their new-found relationship. Season nine opens "the morning after" (more or less), with Rebecca staunchly denying to everyone -- including herself -- that she has slept with Sam. When Rebecca's ex-zillionaire boyfriend Robin Colcord (Roger Rees), now a fugitive from justice, suddenly shows up, he begs Rebecca to tell him that nothing went on between her and Sam -- prompting a surprising response from Sam. ~ Hal Erickson, Rovi
