And Now There's Not Enough.

Last week I was drowning in eggs, and the food bank wouldn't take them, so I put an ad on Craigslist offering free eggs to families in need. I gave away seven dozen eggs in two days. 

But I also got a lot of calls from people who said "I'm not in need, but I'd love to buy some eggs." Of course, I got these calls AFTER I gave away all my eggs. Now I have customers lined up and nothing to sell them.
