Does anyone remember the powerpuff girls riddle?

it was in season 4, episode 45. its called Him Diddle Riddle and i remember the last riddle the girls had to solve was a variant of the truth liar paradox. ms. keane and her clone were tied up and they could only ask one question. the real keane told truth, and the clone told lies. and then blossom made some overly complex question to ask them, but id still like to know what she said.
