When Does "Free" Become a Burden?

I like Craig's List. Really. I think it's one of the greatest things to come out of this Internet thing. And I especially like that people use the "free" category to pass on their hoardes of stuff that might be useful to someone else. Canned cat food, pvc pipe, frames without glass, stained mattresses, lawn gnomes (last year's model). These are just a few of the items listed today in Burlington's free section.

But here's where I draw the line: Diaphragm, only used once. First come, first served.

No, I am not making this up.
