Respect for the homie Pac
NOTE: This ONLY features a few seconds sampled of his voice.

1st, startup OpenIV (if you don't have it I suggest you get it) and go to this location:
GTA V - Mods - x64 - audio - sfx - SCRIPT.rpf

2nd, drag and drop "mc120712v1.oac" into "SCRIPT.rpf"

And BANG! you're sweet.
