 * 10) Spacely for a Day - Spacely convinces all his employees to take an aptitude test and makes sure George scores the lowest. But when Judy, Elroy and Astro alter his father's score to be higher than everyone else's, George is given charge of Spacely's plant for the day when his boss is forced to take an impromptu vacation.
