How many questions hold answers you cannot give?

Yesterday, a bunch of us headed off to check out a Sunday-night pub quiz in our local area. We used to be regulars at the Duke of Kent's Sunday-night quiz, until they sacked the guy who did it and replaced him with a vastly inferior bought-in quiz run by a guy who should never have been allowed a microphone. We've experimented with various alternatives, but nothing's really caught on.

Last night we trotted to the Grove, only to find that their regular quiz was off, and they had a one-night-only replacement. So we still don't know what it's usually like. However, last night's quiz had an interesting schtick that made it quite tactical...
