I didn't know it was McGrath that implemented them, but it doesn't change the fact that Drepper is (IMO) well within his right to say that he does not wish to waste his time by partaking in the joke, and when people again and again try to force him to do so, he is well within his right be grumpy.
The guys that keep pushing the patch are like some nerds I know, who keep making jokes about something very nerdish, e.g. phasers or VAX systems, in a group of people completely indifferent to the subject. Nobody gets the joke, nobody laughs, but they keep pushing the joke, trying to explain why it's funny instead of just dropping it.
