Just the other day I got caught with a flat tire, not just the tube, the whole tire has about a 2" gash through it and I have no idea what I did. Needless to say, I had a spare tube, but I don't carry tires around. So I walked 5 miles to my friend's house with my bike and proceeded to but a similar gash down the middle of my finger trying to open a can of ravioli with a stupid can opener. Insult to Injury.. Or rather Injury to Insult.
I did get the ravioli out, so there was a positive side...
