Super Arthur

S6 E20: Darrin, skipping his Sunday golf to work on a slogan for Larry's new account TOP-POP, sees Samantha and Uncle Arthur standing in the mirror. Arthur pops out, Darrin yells, and Samantha orders the zany Arthur back into the mirror. Arthur pops back in and the mirror shatters. Despite Darrin's pleas, Arthur pops in and out of every mirror in the house, breaking each one. Samantha decides Arthur is ill and summons Dr. Bombay. Larry drops by to see how Darrin is progressing and Samantha has a time explaining a palm tree that Arthur has grown in the living room. Darrin gets Larry out of the house and then decides to sneak off to play a few holes himself.
