i have see dirty work several time and be probably my favourite stan and ollie short . in this one and stan and ollie be chimney sweep and get the job to clean the chimney at the home of professor noodle ( lucien littlefield ) . while noodle be do mad experiment in his lab and stan and ollie cause much chaos try to clean the chimney and make a mess of the living room . the end be where ollie fall into a tank of special formula that noodle us for his experiment and this turn him into a chimp . the best part be where ollie fall down the chimney and load of brick land on his head and but he doesn not seem to suffer much pain from this . dirty work be stan and ollie at their funny . great fun . rating represent 5 star out of 5 .
