"Kill or Be Killed" and "Kill and Kill Again" are truly aweful but they pale into insignificance beside a film I saw in the early eighties called "The Instructor". Of my God! The Instructor was a short, potbellied, hairy fella who could outrun cars. The fight scenes were dire and the sound effects comical. If you can ever find it, watch it. But be warned you may die from laughing.
