Don't you hate it when...
... you're riding along in the early morning snow and some lady steps out into the street, so you lock it up and skid delightfully along the slick pavement, stopping just in time not to kill her, but in the process, your bullhorns slip down in the clamp from the weight you put on them, so you get out your hex wrench to tighten 'em up a little, and then, as you're tightening, you feel that sudden, dreadful looseness that tells you the thing is stripped, and it's 6:45 in the morning and you're on your way to work, so you have to ride carefully on the flats not only for the duration of the morning commute, but for the entirety of the evening commute also? Yeah, well, I definitely hate that.
