- 1805, George Cruikshank, ‎Robert Cruikshank, The Spirit of the Public Journals (quoting a correspondent, "Dangle")
  It appears to me to be saying next to nothing, when they say that such a performer is capital, another inferior, that one has outdone his usual outdoings, and that another has outdone the outdoings of every body else.
