The Ninja Assassins
I just love that scene in Nosh's basement when Sharky faces off with those Oriental killers. One of the most vicious and gritty fight scenes in Hollywood history and Burt gets the best out of it, until they overpower him and he gets smacked in the back of his head.
I used to watch this over and over again when I had it on video. Sheesh, the number of times Burt kicks and punches those goons. I guess he was really angry, because he thought they'd killed Nosh (it was actually Billy Score).
