Cricketer's instincts

I think the last time that I played bingo was in the 1960s ( it was all the rage then) when my father took me to watch a match between Guinness (his employers) and a publican's side in Reading. Playing that day was Tim Tremlett's grandfather ( a county player) and I remember also being impressed in the clubhouse afterwards by a player's Lonnie Donegan impressions.
Anyway local pub quiz on Wednesday ( about mid table but we won it a fortnight ago, thanks) and just before the last round a bingo session ( clearly that's where the organiser makes his cash) and I won. What to call out in the excitement? Sadly and instinctively I went with 'howzat!!'.
