Q: How many congressmen does it take to change a light bulb?A: Five hundred and thirty-five, but only if the following conditions are met: The light bulb will not be changed in an election year. A committee will study the light-bulb situation for at least a year. Taxes will have to be raised. A fair and proportionate number of the light-bulb changers will be from minority groups. No Social Security funds will be used to change the bulb. Each state and congressional district will share in the benefits of changing the light bulb. The blame for the failure of the present bulb will be assigned to the other party. The new bulb will be twice as bright as the old bulb. Because the new bulb is twice as bright as the old bulb, it will cost 130 times as much. A Blue Ribbon Panel will investigate the light-bulb failures and issue a mega-page report to the congress. A fact-finding trip to all countries known to produce light bulbs will be made by most congressmen and their wives. The CIA will investigate the Russian light-bulb-changing system. Details of the Russian light-bulb-changing system will be sold to the Chinese by an American naval officer. The surgeon general will issue a report about the perils of over-bright light bulbs. A program to supply light bulbs to those who cannot afford them will be introduced by Tip O'Neill. President Reagan will give a speech extolling the virtues of kerosene lanterns. Tip O'Neall will initiate a program of free kerosene for the needy. And finally, each and every congressman will send every one of his constituents a newsletter describing how he managed to get the light bulb changed almost single-handedly.
