Some CD's bend farther than a rubber contortionist before breaking, if they break at all; others snap at the slightest provocation. It probably has to do with the quality of the materials composing the CD.
That's the best version of Windows ever made. I used to do that to GayOL discs in the mail, but now I give them to my sister (she does something with them; I don't know what, but it doesn't involve a computer).
In Berkeley, I saw a car that had been covered with CD's to resemble fish scales. I guess you've got to do something with all those GayOL discs...
