The beat behind the verses in Check the Rhime by A Tribe Called Quest is a sample from a Minnie Riperton tune, Baby This Love I Have. They snatched the first few seconds, so you’ll hear something familiar right when you press play on Minnie’s track. I’m really only scratching the surface here; The Low End Theory is riddled with samples.
