The good guys dress in black, remember that
Just in case we ever face to face and make contact
The title held by me, MIB
Means what you think you saw, you did not see
So don't blink be what was there is now gone
Black suits with the black Ray Bans on
Walk in shadow, move in silence
Guard against extra-terrestrial violence
But yo we ain't on no government list
We straight don't exist, no names and no fingerprints
Saw somethin' strange, watch your back
'Cause you never quite know where the MIB's is at
