I watched this episode a number of times that i cannot count but it fascinates me each time.Jerry a fine ventriloquist is sure that his dummy Willie talks to him and persecute him.His agent cannot believe such a story and thinks that Jerry should admit that he is suffering from Schyzophrenia but Jerry doesn't see things this way and continues his show. Later that night however he will hear a weird and frightening voice that makes him crazy..The dummy in the episode really seems to be alive and is threatening till the surprising end. Who' s who? I had no answer at the end of the episode but i have a little idea..a very good episode that remains among the best.I recommend it.
