'owzat

From Tardis Wiki, the free Doctor Who reference

'owzat! or Howzat! was an exclamation heard on the cricket ground. It was once heard, for instance, when the Fifth Doctor was playing in a Stockbridge Cricket Club match. (COMIC: The Tides of Time) Later, the Doctor said it rhetorically after he used a gigantic ball to effectively bowl over a couple of Tractators on Frontios. (TV: Frontios)

Behind the scenes

Although never defined in DWU, it was simply a general interjection used by fielders to attract the attention of an umpire, in the hopes that a call might be reversed.
