I got this e-mail the other day:
Found your blog post http://pissedoffteeacher.blogspot.com/2009/05/silver-not-for-my-hair-or-my-car.html while searching for potential link partners for XXX.com. I was wondering if you would consider linking the words "Honda Accord" to http://www.XXX.com/ "Pathfinder" to http://www.YYY.com/ and also add a link to ZZZ.com at the end of the post.
In return I would send you $20 for doing so.
I'll gladly give it away free if I like you and you are worthy, but I'm not cheap!
