My favourite peer review story is when I submitted one on my articles to the top journal in my field at the time (Appied and Enviromental Microbiogy). It came back with the usual peer review trivial changes (cite this irrelevant paper of mine,etc) which I did (this nearly always easier than arguing with the reviewers). The editor made a mistake and instead of sending the updated manuscript out to the original reviewers, they sent it out to a new lot of reviewers. What was funny about the whole exercise was the second set of reviewers called the first set of reviewers idiots and told me to change everything back.
