i've never seen it used for pleasant surprises. its basically if you want to show something (even something that does not work, like the engine-not-starting) and the demonstration does not work as expected.
They only have to be "unpleasant" in some aspect, for example because you now annoyed/bothered you team lead.
The unexpected behavior itself can still be desired, with the unpleasantness restricted to the demonstration itself.

Is the word only for unpleasant surprises, or for all such situations, even when the surprising outcome is also a good one?
