Yet another "How many (this space for rent) does it take to screw in a lightbulb?" joke

No doubt, Sartre would have a simple, one word reply to this one. "Merde."

Q: How many existentialists does it take to change a lightbulb?

A: Two. One to screw it in and one to observe how the lightbulb itself symbolized a single incandescent beacon of subjective reality in a netherworld of endless absurdity reaching toward a maudlin cosmos of nothingness.
