When have you seen the raw, dark side of fighters?

Boxing is a sport that goes hand in hand with violence. Beyond all of the façade that fighter's necessarily sport, these are normally guys who came from the street and have a raw mentality. So I ask- when have you seen the veil slip? When you get to see glimpses of that street mentality? I remember in the run-up to Hatton Mayweather, where Floyd was whispering in his ear 'move and I'll break your jaw, move and I'll break your jaw'. I remember thinking 'damn', beyond the smiling faces this guy is kinda raw.
