Kajunkenbo: an episode of the TV show Fight Quest. Kajukenbo is a hybrid martial arts style from Hawaii and the USA. It's anything-goes street fighting, much like Krav Maga.

The episode shows some awesome self-defence training. The principles the masters are talking about are pretty much the same ones we've got in Krav-Tardemet. Watch the whole episode (49min), it's worth it.

Great stuff they do (which we also do in Krav-Tardemet):

Anything goes. It's a street fight, not a ring fight.

Self-defence scenarios.

Surprise attacks and stress training.

Defences against weapons (sticks, knives)

Don't wait your opponent out. Go for it and take him down ASAP.

Connect all your counters and attacks together. Never stop moving your body.

Finish him quickly and be ready for the next guy.

Some apparent differences between Kajukenbo and Krav-Tardemet:

Technique-wise they don't place the same emphasis on what we call the V in Krav-Tardemet, that is moving next to your attacker's shoulder with your first counter. This gives you a vital positional advantage.

We aim more explicitly for knock-out points, which helps especially women beat larger, stronger opponents.

In Krav-Tardemet we consider the options of knocking out an opponent with a strike to a pressure point (rather than brute force) or locking them and forcing them to walk with us (rather than necessarily breaking a joint). But if they have a knife and two friends, sure, break their elbow.

We do not kill an attacker with their own knife. It's self-defence, not the military.

All of these are just my brief impressions. Obviously I know a lot more about Krav-Tardemet than Kajukenbo, so I can't be exactly sure of all this. You can only show so much about a martial art in a 49 minute documentary.
