Who is Super Terry?

I am a head custodian and my name is Mr. Terry,

I’m kinda a big deal like peanut butter and jelly, 

The youth think I’m cool because I can rap, 

Plus they know Mr. Terry always got their back,

So if you see a mess, chill don’t worry, 

Somebody will be there, quick n’ a hurry, 

But if you make a mess, it’s okay, 

because I’m about to show you 

The Super Terry way!
