slight tinge of the comic. But let us go further still, and suppose that our attention is attracted to the material side of the metaphor by the choice of a relationship which is incompatible with the gender of the two words composing the metaphorical expression: we get a laughable result. Such is the well-known saying, also attributed to M. Prudhomme, "Tous les arts (masculine) sont sœurs (feminine)."
"He is always running after a joke," was said in Boufflers' presence regarding a very conceited fellow. Had Boufflers replied, "He won't catch it," that would have been the beginning of a witty saying, though nothing more than the beginning, for the word "catch" is interpreted figuratively almost as often as the word "run"; nor does it compel us more strongly than the latter to materialise the image of two runners, the one at the heels of the other. In order that the rejoinder may appear to be a thoroughly witty one, we must borrow from the language of sport an expression so vivid and concrete that we cannot refrain from witnessing the race in good earnest. This is what Boufflers does when he retorts, "I'll back the joke!"
