It's more like... The first to buy one and change it. The second to tell the world that because it was him who repeatedly complained that the lightbulb should be changed, and he did help to grab a non-contact voltage detector and ladder while the first was working on it, hence they should be called "GNU/Linux" lightbulb changers, not "Linux" lightbulb changers, despite him not being the one who actually changed it.
