"This brings up the interesting question of introducing two people to each other, neither of whose names you can remember. This is generally done by saying very quickly to one of the parties, “Of course you know Miss Unkunkunk.” Say the last “unk” very quickly, so that it sounds like any name from Ab to Zinc. You might even sneeze violently. Of course, in nine cases out of ten, one of the two people will at once say, “I didn’t get the name,” at which you laugh, “Ha! Ha! Ha!” in a carefree manner several times, saying at the same time, “Well, well—so you didn’t get the name—you didn’t get the name—well, well.” If the man still persists in wishing to know who it is to whom he is being introduced, the best procedure consists in simply braining him on the spot with a club or convenient slab of paving stone."
