A prisoner at the Edmonton Max started training a large fly to do tricks.For years, for thousands of hours, he worked with the insect. It learned to walk across a miniature high wire, ride a tiny one-wheel bike, balance on a pair of stilts and sing songs from PHANTOM OF THE OPERA. When you and I get out of here, the jailbird said to the fly. were going to tour the nightspots and make a fortune. Finally the day arrived. Fly safely tucked away in his pocket, (inside its matchbox home), the ex-con made his way to a bar to celebrate. At the bar, he brought out his trick fly. On cue, it started moonwalking. What about this fly, eh? he said to the bartender. In one swift motion, the bartender reached for his copy of the newspaper THE EDMONTON SUN, rolled it up and squished the fly with a mighty swipe. Glad you saw it, muttered the bartender. Blasted things are eve rywhere.
