Near work: young kid with dereilleur jammed between cluster, spokes and seat stay. Chain broken. Lug all twisted and unrepairable looking. Somehow he'd pulled the mother of all chain-sucks and ripped his dereilleur clean orf!!!

Kid: "D'ya reckon they'll be able to fix it?"
I wasn't confident.
Kid: "Damn. I had a long ride planned for today"
What could I say? He wasn't going anywhere for a while
