What was the name of Roy Rogers’ Horse?

On the rare evenings when they weren’t entertaining, Garry and Tina read through the answers on their Trivial Pursuit game. Sometimes for fun they asked each other the questions, but occasionally, especially before a big dinner party, they’d just cram. Tina studied the History, Literature and Entertainment questions and Garry, an engineer, handled the Geography, Science & Nature and Sports categories. In an impressively short time they’d worked through the entire box. When it came down to playing a postprandial game with their guests, the challenge was in affecting just the right air of uncertainty before shouting out the answer.
