When Reginald was home with the flu, (unh-huh-huh)
the doctor knew just what to do-oo.
He cured the infection
with just one small injection,
while Reginald shouted out in-ter-jec-tions.

Hey! that smarts!
Ow! that hurts
Hey! that's not fair, givin' a guy a shot down there!

Innnn-terjections! show excitement! or emotion. And are generally set arpart from a sentence by an exclamation point, or by comma when the feeling's not as strong.
