Wanted to customize xjack for my screensaver to say "All work and no play makes Zach a dull boy." So I searched through xjack.c. He's the source for that bit:
static const char *source = "All work and no play makes Jack a dull boy. "; /* If you're here because you're thinking about making the above string be customizable, then you don't get the joke. You loser. */Call me a loser, I'm still going to make the change.
PS. Don't leave me comments "explaining" the joke.
