I was just talking about this on my KMOX show...
Dean Cameron is an actor/comedian who had some free time and decided to have fun with the spammers behind those Nigerian e-mails that promise you wealth if only you'd help them out. Dean took on a phony identity himself and replied, "Great! Do you have any toast?" And thus it began, seven months of fun never giving in but wasting as much of the spammers' time and mental energy as possible.
I saw Dean perform the transcript of this exchange, verbatim, in a two-person show (with Victor Isaac as the bewildered Nigerian), and it's hilarious. This month, they're doing it at the Edinburgh Fringe Festival, but you can read it here.
