Fall From Great Heights
Option 1: Hop on another guy's back
Seen in: The Bourne Identity If you're trapped in the stairwell on the fourth floor of a building, and there are people below you shooting at you, simply take the corpse of one of your earlier victims (trust me, if you're in this situation, you've got some victims already laying around). Grab onto his back and jump down the four stories, all the while shooting guys on the way down. When you hit the bottom, the other guy will absorb 100% of the impact, and you can be back up on your feet and jogging out the front door.
Option 2: Wear lots of rubber
Seen in: The Dark Knight If you expect to be in a situation where you'll be falling a great distance, wear protective gear ahead of time. It doesn't matter if it's so frail it can't stop a knife from being jabbed into you by your lover, it will still suffice to protect you from any pain or negative effects from falling six stories and landing on a taxi.
Bonus: If you're implementing Option 2, you can easily let someone else cling to your back, thus using Option 1 as well.
