President Clinton: (Something's got to be done...who are all these people?) Zonker: Bill Clinton's White House. Gridlocked, paralyzed, completely overwhelmed by...mail! Bags of it! Mountains of it! More mail by far than any President has ever received! All this mail has to be answered, of course, but with White House cutbacks, who's left to do the job? Volunteers, that's who! Ordinary, selfless citizens who work day and night to keep ahead of the load! If you think you'd like to help out, then write the President at this address: The White House - 1600 Pennsylvania Ave. Washington, D.C. 20500! That address again... Mike: Uh...Zonker?
So this was why Al Gore invented the Internet! :-)
