Crowning the greatest rapper of all time may be a fool's errand -- though some have tried

Los Angeles rapper Murs, however, just secured his place as the MC with the longest continuous flow in the world, with a 25-hour rhyme-spitting marathon.

The 38-year-old rapped over his own music as well as classic hip-hop artists like Wu-Tang Clan. He received only a 5-minute break each hour and concluded this morning around 11 a.m. MT.

Watch the final two hours of the world-record rap session above.
