In the conclusion of a two-part story, Diane (Shelley Long) defies Sam (Ted Danson) by agreeing to have her portrait painted by arrogant artist Semenko (Christopher Lloyd). Hoping to mend their differences, Diane wants Sam to accept the portrait as a work of art on its own terms. But Sam is so mad about the whole project that he can't see straight -- and it looks as though the romance between Sam and Diane has come to an abrupt and noisy conclusion. This was the final episode of Cheers' second season. ~ Hal Erickson, Rovi
