Confronted by a robber in his Chicago bedroom, best-selling author Studs Terkel pulled out a wad of cash, and it was hastily grabbed. But Terkel wasn't cowed. "I said, 'Hey, I'm flat broke now, gimme 20 bucks,' " the 87-year-old former radio host and Pulitzer Prize winner said of the late-night break-in. The unmasked robber complied, handing back a $20 bill. The experience was "simply dreamlike," the effervescent Terkel told ABC-TV, "as if somebody choreographed a slow dance at midnight."
