कुशकसवलम्बनन्यायः

As a ship-wrecked person in making struggles for saving his life, catches hold of an even a straw that he comes across (if he cannot get any ting thing more solid) though quite in vain, so a person in course of a debate, when he fails to gain his point by a strong argument, takes recourse to a frivolous one, and thus becomes only a butt of ridicule.
