Also loved the part in Godfather One where Sonny sees that his sister was beat up by her husband and he gets so angry he bites his own hand,,,then he goes out in the street and absolutely destroys his brother in law...I love the part also when the brother-law was trying to hold on to some bars and sonny bit his hand so he would let go.....classic street fight...
Sonny was a crazy mother-fucker!!!!....however his temper was his downfall in the end
