When Samantha complains that Darrin has been forgetful of late, helpful Endora casts a spell on Darrin's wristwatch. So long as he wears that watch, Darrin will be possessed of a photographic memory. Unfortunately, Darrin's newfound facility at conjuring up facts, statistics, and trivia at a moment's notice does not rest well with his know-it-all client, Ed Pennybaker (Dan Tobin). Written by David V. Robison and John L. Greene, "I Remember You...Sometimes" was first telecast on February 16, 1967. ~ Hal Erickson, Rovi
