In this week’s magazine, Tina Fey writes about the lessons she learned as a writer on “Saturday Night Live.” Fey and other women use the ladies’ room; “the men urinate in cups.” Harvard graduates write “commercial parodies about people wearing barrels after the 1929 stock-market crash”; improvisers from Second City create “loud drag characters named Vicki and Staci screaming their catchphrase over and over.” Click over to the site for more vintage Tina Fey video.
