Mark+the+Shark;interjection

Then, while swimming through the park he spotted something big, like a shark! He was scared, but decided to ask for some advice anyways.

"Hello fellow, WOW! your bigger than i thought, anyway i was wondering if you could tell me what an interjection means?"

Suprised the big creature replied "I'm Mark the shark, and my friend you just happened to use one yourself!"

Words like WOW! or Jeeze! anything that pretty much shows expression, would be an interjection.

"got it! Im on my way"
