That reminds me. In college, hurrying to get to my first class in the morning, the brake lever on my bike fell off and was bouncing around in the spokes of the front tires. Do I stop? Heck no! Pedalling like a maniac I lean over the handlebars and try to pull the lever out. As I watched it turned perpendicular to the wheel, hit the fork and the wheel stopped dead. Faceplant on the sidewalk. OUCH! Live and learn.
