Tweets
Looking for tweets for ha-ha.

ruzuzu Hannah: Are you a journalist?
Bernard: (Shocked) No!
Hannah: (Resuming) I've been in the ha-ha. Very squelchy.
Bernard: (Unexpectedly) Ha-hah!
Hannah: What?
Bernard: A theory of mine. Ha-hah, not ha-ha. If you were strolling down the garden and all of a sudden the ground gave way at your feet, you're not going to go 'ha-ha', you're going to jump back and go 'ha-hah', or more probably 'Bloody 'ell' . . . though personally I think old Murray was up the pole on that one - in France, you know, 'ha-ha' is used to denote a strikingly ugly woman, a much more likely bet for something that keeps the cows off the lawn.
(This is not going well for Bernard but he seems blithely unaware.
Hannah stares at him for a moment.)
--From Arcadia by Tom Stoppard May 8, 2012
olof1935 Came across this wonderful expression in a Mary Balogh book. Need to learn how to add a definition as nothing so far comes close to describing what was and continues to be an awesome landscaping effort from as far back as the time of William the Conqueror. Most interesting is, according to Wikipedia, the note that "The Ha-Ha fence was inspired by Orientalism and the Japanese gardening ideas of concealing barriers with nature." Calling such a ditch seems less than. Mar 8, 2009
