The Twilight Zone Episode 1.01 The Comedian

Comedian Samir Wassan (Kumail Nanjiani) wants to be famous...but at what cost?

Struggling comedian Samir Wassan meets his idol J.C. Wheeler, who advises him to focus on his personal life. Wassan makes jokes about his dog and gets laughs but discovers to his shock that not only did his dog vanish, but no one seems to remember that it ever existed. He learns that jokes about the people in his life get guaranteed laughs but cause them to disappear from existence. After accidentally erasing his nephew, he starts erasing people he thinks the world would be better off without. His girlfriend Rena breaks up with him after one of the people he erases causes her to go from being a successful lawyer to a struggling waitress.

Wassan continues abusing his power, going so far as erasing rival DiDi Scott, until Rena confronts him during a set with a journal of names of people he has erased. Realizing he has become a selfish monster, Wassan erases himself from existence, creating a timeline where he never existed and everyone previously erased continues to exist. Didi, now a rising star, meets Wheeler following a set and asks for his advice.
