on my commute home, i was cruising along, and passed a couple of guys who squeezed through the gate at the back entrance of my uni. nearly to that gate, i felt a tug on my right foot. my shoelace had wrapped around the pedal/crank and with each revolution, was squeezing tighter. in about 2 seconds my foot was tightly tied to the pedal. i frantically backpedaled to unwind, but alas, i was on a fairish hill....the bike promptly crashed to the ground. as i slithered around trying to free myself from my bondage, i heard the guys call, you ok? great, just great! oops. i'm sure they just assumed i was a klutz who can't ride a two-wheeler i guess it could have been a great ending if they rushed to my aid and rescued the damsel in distress, but as it was, i finally untangled myself, leaped back on the bike, and pedaled the HECK outta there!
