"Do it like that!" – just CANNOT find this!

Please help me before I lose my sanity. I’ve spent the best part of five hours now searching for songs with the lyric "Do it like that", you would not believe how often that phrase has been used. I thought it was from ‘Fort Minor – Petrified’ but no dice. Anyway I’ve attached a small clip of the vocal in a track… I’m thinking it’s from something in the era of all those classic DJ Supreme acapellas but could be wrong.

So many people I’ve asked have gone "sure, of course I’ve got that, it’s a classic vocal sample" but it is as if this has been erased from time! Help! :/
