What is the Worst Email "Reply All" Gaffe You Made or Heard Of?

Posted by Alan Childress

We ask you to Comment with the best/worst example.  On the heels of this WSJ Law Blog post on Skadden/Sheila Birnbaum's sending an email errantly to reporters that questioned the Mississippi AG's views, and the earlier Pepper Hamilton mix-up of a reporter's name with a co-counsel's (oh that pesky auto-complete function), I am reminded of a time that I meant to forward my boss's email on to someone else with the view, I duly added, that my boss was insane.  Instead, I 'Replied' it to the boss.  Fortunately he was insane, his email was insane, and he did not seem to register the insult, likely knowing he or his email was insane.  So it's all good.  What's your example?
