KRS One MC's Act Like They Don't know sample

Hey, I can't remember where this vocal/shout sample came from. Any help is much appreciated.

sample appears right before the drums come in

peace

that sound almost like a bird/crow caw sound?

Interesting thought since Premo used birds on "Nas is like"
But I guess it is a vocal from reggae/dub. Kind of U-Roy.
Here at 1:46


It also reminds me of a sound from Duke Nukem 3d
Wait......damn thats a good idea....I'll get me a beer and kill some aliens. 'Come get some'

peace

hell yeah..

actually, i got a ton of mileage from those kinds of sounds... from rise of the triad, and stuff like that. Those PC games from that era came with a folder with every sound in the game
