Tupac may be dead, but his temper lives on forever.
After Allen and Albert Hughes fired Pac in 1993 from their seminal film, Menace II Society, Shakur spearheaded a physical attack on Allen.
A few years ago, the brothers opened up to Complex magazine about the infamous altercation.
"Tupac hit him from behind," Albert said. "Allen turned around and threw him on top of the car ... Tupac was like, 'Go get my chain!' and he let everybody else go at my brother. Allen got beat up by like 15 guys but he stayed on his feet."
On this day in 1994, Pac began a 15-day jail sentence for his role in the attack. And to commemorate, we've gathered some of our favorite Tupac freakouts. Check 'em out after the cut.
