This is hilarious. First, why do they even make aphrodisiacs for men? Is there some large group of men uninterested in sex? Men do not get headaches, or if they do the cure is obvious. Next, with all of modern pharmaceuticals and the thousands of products on market for hydraulic failure why would one choose "toad venom?" Then, this fellow injests it even though the witch doctor instructions clearly state it is to be rubbed on the skin during a full moon.
Finally, he probably thought it would get his love life hopping!
