That One Song

Hilarious mental image: 

Sheppard Riley in his night camo uniform, yelling at the recruits he's training for the CIA's secret paramilitary unit  . . . except instead of yelling, he's singing "I'll Make a Man Out of You" from Mulan.

You'd never actually get him to do it because he doesn't like singing in front of people. However, if the story was a musical for some reason, he'd have a song like that. At the beginning, before all the crazy stuff started happening.
