I once applied for a job, and was rejected with a letter listing reasons why they typically reject applicants. This list included grammatical and spelling errors on one's letter or resume. Ironically, the company's rejection letter itself contained both a grammatical and spelling error. Having already been rejected, I decided to write back to them and point this out. I guess they were in some way impressed, as they wrote back to me asking if I'd be interested in a job, but by this time I wasn't.
