Once again, Jim (Christopher Lloyd) has been carried to extremes by his latest enthusiasm. In this instance, Jim is obsessed with notion that, in order to experience full happiness, one must be generous with those less fortunate than themselves. Thus, Jim hands each of his fellow cabbies 1000 dollars -- on the condition that they immediately give it away. Busy character actor Tracey Walter has a small role in this, the final Taxi episode filmed (though not the final one to be shown). ~ All Movie Guide
