Q:  How many existentialists does it take to screw in a lightbulb?
A:  Two.  One to screw it in and one to observe how the lightbulb
    itself symbolizes a single incandescent beacon of subjective
    reality in a netherworld of endless absurdity reaching out toward a
    maudlin cosmos of nothingness.

Five is a sufficiently close approximation to infinity.
