Just got back from a pub quiz where we (my team) came 2nd, one question was "How many black keys are there on a piano ?". I am not a piano player but I do have a piano, my answer was 35 the quiz master said 36 and this single point was enough to lose the quiz (and the £25 food/beer voucher). Being a sad b@$t@rd , when i got home I had a look at my piano, IT HAS 35 BLACK KEYS. Do I have a deficient piano or am I justified in giving the quiz master sh$t next week?
