Watson the Jeopardy! Supercomputer Said “What Is Leg”

“Watson answered incorrectly four times on Monday night. For example, Watson answered, ‘What is leg?’ for a reference to the one-legged 1904 Olympian George Eyser. The correct response was, ‘What is, he’s missing a leg?’ Neither of the human contestants correctly answered that question either.” — After one day of battle, Watson the velvet-voiced machine is currently tied for first with human Brad Rutter in their three-day Jeopardy! deathmatch, continuing tonight and tomorrow. Ken “74” Jennings currently brings up the rear. What is leg.
