S04E20 Alien Hunter

Title: Alien Hunter Plot: On the eve of Dick's birthday, he has enlisted Sally, Harry, and Tommy to organize a surprise celebration. During class, he encounters a woman named Charlotte Everly, who seems captivated by his intellect. Initially claiming to audit the class, she later identifies herself as a journalist and then an enthusiastic admirer. Charlotte, along with her son, cleverly inserts themselves into his birthday festivities, ultimately canceling the party and imprisoning the arriving guests in the basement. She then reveals to Dick that she knows he is an alien and intends to perform surgery on him. Kathy Bates makes a memorable cameo, reminiscent of her iconic role in Misery when Dick refers to her as his "biggest fan."
