led zeppelin's "when the levee breaks" drum beat in biz markie's "just a friend"?

i just heard the biz markie song in an episode of It's Always Sunny in Philadelphia (hilarious show by the way), and noticed that the drum beat in the song sounded very similar to when the levee breaks by led zeppelin. Does anyone know if Biz Markie sampled the drum beat? Here's a link to the song:
