"Think Twice" required an incredible amount of creativity for the Imagination Round.
It's an obscure title, so for anybody not familiar with "Think Twice," I'll just describe the Imagination Round using the one episode I have as an example.
Two teams of two play. One team has to guess a subject--well-known person, place, or thing--from clues given by the opponents. The opponents are given a list of nine Password Plus-style clue words to the identity and must improvise a story using as many of those words as possible (at least five), the incentive being that the more clue words you use, the higher the point value for that subject (10 points per clue word). So for the episode that I have, the team seeing the clue words improvises this story, which I'm paraphrasing...
I don't like to do public speaking very often because I have a tendency to get tongue-tied. But one day I had to give a speech, and I wanted to look my best, so I put on a nice lace dress. I approach the platform and I realize the adrenaline really pumps inside me when I'm starting to speak...
The team doing the guessing would win the points if they guessed that the subject was "SHOES." Clue words: tongue, tie, lace, platform, pumps. Wrong answer gives the points to the team that told the story. My jaw dropped the first time I saw this played I thought it was brilliant.
