I agree with Sixxer. However, you'll need to come up with a better story than 'i fell on the side walk' for the ladies. I would suggest something along these lines:
1) Kicked while killing a ninja with your other hand. (this is more to impress/scare your fellas)
2) Rescuing a small puppy from a 4th story ledge, when you fell...
a) ... and saved the puppy while breaking your arm. (this might work)
b) ... and the puppy broke your fall, but your arm hit the ground first. (might not)
3) Broke arm hitting your girlfriend, cuz she looked like she needed it. (yah, this wont work at all)
Good luck on the recovery.
