laser-scope your loved ones is right up there with my all time favorite cartoon from the 80s...
"So many men, so few bullets."
google credits the quote to Adrienne Gusoff. ABC reckons a female politician from 80s had the poster in her office. I remember it as a cartoon.
A classic exercise in identifying minority humour. Is it funny if you change the object from men to women? No.
Modern versions include "So many terrorists, so few bullets" Darkly twisted.
But not as lightly twisted as xkcd.
