Where she's a young Elementary Student and the President's Daughter, Amy Carter, is in her class. I THINK it was Lorraine Newman playing Amy. Anyway....She starts cheating by looking at Radner's paper. Radner starts screaming...... AMY'S CHEATING!!!! AMY'S CHEATING!!!!! That leads to Secret Service guys busting in and beating the hell out of Radner. I saw that LIVE, probably around 1977, and have not seen it since. But it has always stuck with me. That skit and Carrie Fisher on there around the same time, Playing Princess Leia as a Surfer Girl on a cheesy Beach Flick, are two of my earliest memories of SNL.
