I used to. When I had a couple roommates back 25 years ago, on St. Patrick’s Day the puzzle was an “event”. St. Patrick’s Day Parade was the puzzle with only a period and an apostrophe visible. I solved the puzzle with NO letters showing before they even spun once. My roommate just about fell over dead. Never done it since.
Actually was in the crowd when they filmed it in Burbank years ago. When they started the show, we were all expected to cheer, but we weren't loud enough, so they had to restart it. They film two shows back-to-back.
