RUDENESS-TO-REAGAN AWARDS Take a Lesson From Avis, Sam ABC's Sam Donaldson has come in second to House Speaker Tip O'Neill in a list of the 10 most ill-mannered Americans. (How my mother-in-law missed being included amazes me, but that is a matter for another day.) The Speaker got top marks for his rudeness to President Reagan during those televised speeches when viewers can see O'Neill and Vice President Bush behind the President. Etiquette writer Marjabelle Stewart, who compiled the list, claims that O'Neill's paper-rattling and yawns are prize winning examples of uncouth behavior, while White House correspondent Donaldson's shouts and baited questions during news conferences are only second-rate. Donaldson is rumored to be taking the defeat pretty hard. For help, he turned first to his greatest admirer. DONALDSON: Mirror, mirror! On the wall. Who's the couth-less of them all? MIRROR: Sorry, Sam. You're a pussycat compared to O'Neill. I mean, he tells jokes to the Veep while Ronnie's talking. You can't top that act. Realizing he needed professional help, Donaldson hired a rudeness consultant. CONSULTANT: You've just got to try harder. It worked for Avis! DONALDSON: Maybe if I sneered a bit more? CONSULTANT: You've maxed out on sneer, Sammy. People can barely understand you now through those twisted smiles. DONALDSON: What then? CONSULTANT: Had you thought about some spicier comebacks to Reagan's answers? "Following up on that, sir ..." isn't much of a riposte? DONALDSON: Waddaya have in mind? CONSULTANT: How 'bout "Bullshit, Ronnie." DONALDSON: Not bad. CONSULTANT: And you're missing a lot of opportunities there at the helicopter pad, too, when the President leaves for Camp David. If he leaves with the First Lady, shout out "Going off for a nooner, Mr. President." And if he leaves alone, yell "A little on the side this trip, sir?" You'll be on top of that list in no time. DONALDSON: You've really earned your money. The word is out in Washington that Speaker O'Neill is prepared to fend off any bids that Donaldson makes for top slot on the rudeness list. During the next Presidential speech from the House chamber, look for O'Neill wiggling a couple of fingers behind Reagan's head like rabbit ears.
