Although long extinct from television, On Whew!, Tom Kennedy did not always following up his saying only one block on the sixth level, with, "that is if you choose." I also recall once watching an episode and the contestant called for one of the clues on level six with lots of time on the clock. The player either gave a wrong answer to the "blooper," or hit a block, losing five seconds. The player then said "Longshot," and Tom Kennedy looked lost, and was cued or realized himself, the player could not call "Longshot," once he/she was on the sixth level. If it were allowed, potentially there could've been just an incorrectly answered clue revealed on the board, and lead to being blocked out.
