How many audiophiles do you need to change a lightbulb?

Hey, don't forget the room treatment.  Need black tiles for light absorption and mirrors for reflection, crystal prism for refraction rainbow colors and disco balls for diffraction so you have optimal lighting that affects overall performance.

If I had a light bulb installed on the tail of my wife's rocket and she turned it on at the instant she sped away at the speed of light to catch the end of the closeout at Payless Shoes, would I be able to tell if the light is on as she flew away?

Two or more.

only one to screw it in (though the 1/4" brushed aluminum base is much heavier than it needs to be), but at least one more to argue that you need to replace the tungsten filament with something more neutral.

I do hope Total Contact was used on the contacts, in eight weeks it will shine brighter!
