The Secret World of Alex Mack, Season 1

Vince Carter:
...We're going to Atron Junior High disguised as janitors. Once we infiltrate the premises, we'll go on watch to find the child.

Dave Watt:
To be honest, I don't know the first thing about being a janitor, Vince.

Vince:
(irritated) Well you obviously didn't know anything about being a truck driver but that didn't stop you, did it?

Dave:
That's true. OK, I'll take a shot.

Vince:
(grabs Dave's shirt collar and pulls him in) This isn't a matter of choice, Dave.

Dave:
What does a janitor do?

Vince:
It doesn't matter! Once we get there just keep your eyes open for something unusual. Any display of extraordinary behavior or power. This child that we are looking for could possibly hold the secrets to our future on this planet!

Dave:
Wow… I didn't know being a janitor was such an exciting job!
