This morning, while riding home from Shul, my bike's chain managed to get derailed. Luckily, I was in a location where I could easily pull off to the sidewalk and fix it. But before I did, I popped open my bike bag and pulled this guy out:
That there would be a roll of atheltic tape stuffed with a pair of Nitrile glove.
I put the gloves on and went to work. Within 15 seconds I had my bike back in business, minus grease covered hands. Score one for being prepared.
