I was at this open mic last night when one of the comics asked if anyone in the audience knew what "the stranger" is.
I said, "Yeah, it's a book by Albert Camus, dealing with existentialism."
The comic responded, "What? No! Huh? Think lower-brow."
Turns out it has to do with making your hand fall asleep and then masturbating, making it feel like someone else is doing it.
So, I was close.
