My favorite anthology entry, at least for today, would be the Tales from the Crypt episode "The New Arrival." It is perhaps the most memorable short-form horror I have ever seen. Scary, moody, great performances, a killer ending, and infinite replay value=a huge win all around. And in general, it just creeps me out in a way few things can. Can't put my finger on exactly what it is, exactly, but I like it. Second place would probably go to "The Cat from Hell" in Tales from the Darkside: The Movie.
