Taking back my "Wow"

Amusing anecdote:

Earlier (i.e. five minutes ago because the joke won't be funny in another five minutes), I'm fiddling around with a trivia game on my iPhone when the category "Physics" comes up. Surprised and a bit impressed, I think "Wow. Really? Ok, let's do this." and wait for the question.

"The study of animals is called what?" pops up on the screen.

I want my "Wow" back.
