Good point on 20 Questions, Tim. Each card has a mix of clever and pedestrian clues - others on that same card go "I'll melt in the sun", "I'm always cold", "I'm made with milk", and "Most often, I'm chocolate, vanilla, or strawberry", along with occasional instructions like lose turn, take a free guess, and exchange places with so-and-so player (correct guessers along the game board the number of clues remaining. If a player guessed after 5 clues read, the reader moves 5, the guesser moves 15 spaces). I can see some Jackpot riddles at least inspiring some of the clues. About that time, though, there were lots of box games using the same concept - Anybody's Guess and Clever Endeavor immediately come to mind. During the adult board game boom of the 80s, there were many box games that generously borrowed TV game show concepts old and new, too. Just goes to show good ideas rarely die - they just change.
