This is a song about "Mr cunningham"

Like mr. sandman i am the closer/

While you starin' over your shoulder

People thought it was mr bruce wayne

I don't toot my own horn but i'm a cold train

Shouts to mr rizzo

Double m g forever though

Said when i do dirt wit her

You be tapping like a mr

I call em up, they might fall through

Mr coleman, i'm coming for you

You is not hip then i can not coach her

Cause i am a rap master mr. buster
