Allan: What are you doing Saturday night?
Museum girl: Committing suicide.
Allan: What about Friday night?
Weekend Plans
Explanation
The humor comes from the dark and unexpected response from the museum girl. Allan asks a casual question about her weekend plans, and she replies with a serious and morbid statement about committing suicide. Then, Allan casually asks about the day before, as if she already made plans for saturday without asking him about Friday night, which is funny because of the contrast between the mundane question and the seriousness of suicide.
