办公室笑话

One day I was in commute reading my emails through my balckberry. I found one email titled "August 4", but the contents was for some arrangements of the Labor day. Realizing this is a mistake, I sent an email back to the author, politely hinting there is a mistake in his email. So I said "When is August 4?". A few minutes later, he replied "August 4 is in September".
