An Irishman visited Scotland to take in the good fishing, but all day he'd had no luck. A Scot passing by noticed the glum look on the Irishman's face and inquired as to the problem. Informed that the fish wouldn't bite, he asked the man to pull in his line. On the end was a small worm. "Ach," said the Scot, "That's the problem." Whereupon he pulled out flagon of scotch and poured it over the worm. "Try that." The man recast, but as the Scot was walking away he heard a shout. "Help, help!" Turning, he saw the Irishman struggling with the rod. "What's the matter, is it hung up on a rock?" "Begorrah, no! The worm's got a six foot trout by the throat and he won't let go!"
