I remember one Pathfinder game where the contestant guessed right and the correct number lit up on the board behind her. But the next correct number (6) was mistakenly lit up as well. So the contestant had the choice of 3 numbers. The WHOLE studio audience was screaming frantically, "SSIIIIXX!!!" The lady went, "I guess...six?" Then Bob told her what had happened. Before she made her next choice, she looked at the board behind her, just to make sure the mistake didn't happen again. lol
