Make Love Not Hate (S06E30)

Esmeralda has been jilted and arrives at the Stephens home in a very depressed state. Samantha is worried about her and calls Dr. Bombay. His diagnosis is she needs another man to bolster her ego and produces a cure in the form of Norton. At first, Norton thinks that Samantha is the girl Dr. Bombay has for him, but his excitement is short-lived when he discovers it's Esmeralda he is destined for. To help things along, Dr. Bombay makes a love potion which when taken causes you to be smitten by the first person you see. Samantha is expecting Darrin, Larry, Mr. Meiklejohn, (a very important client) and his wife at any moment for dinner. In her hurry to get Dr. Bombay, Esmeralda and Norton settled, she knocks some of the potion into the clam dip. (iTunes)
