Perhaps we do: and for some solvers a trigonometric method can also be both Haha and exciting.
"Haha" has been used in these recent discussions to mean something like "silly" or "not my idea of real geometry", and has been attributed to Martin Gardner. Gardner's word was "Aha!", not "Haha". He used it to imply unexpected "insight" or "apprehension".
My thanks also to you, Narisimham, for contributions to the discussion of adventitious angles and puzzles about them.
