When did Craigslist jump the shark?

Where we live, we frequently have wealthy people come in to work on business for a few months.

We became suspicious when the woman started sending e-mails praising Tebow in the middle of the correspondence. We had pretty much figured it was a scam when the woman said she would meet us.

I warned my wife that they were going to send a large check, so we knew once they sent it, it was a scam.

Funny thing, a few days later, a guy called asking us about the check. We told them we never got one. The guy cursed, then hung up.
