In "The One With Russ", Rachel dates a man named Russ, who to the bewilderment of her friends looks and acts eerily similar to Ross.

Eventually, when Rachel sees the two arguing, she finally sees the similarities between them and walks away, disturbed. She later breaks up with Russ, who consequently becomes depressed and one day while hanging out at the coffee shop is spotted by Ross' ex-girlfriend Julie, who is likewise depressed after Ross broke up with her.
