I don't know about you, but I find those "Out-of-the-Office" e-mail auto-replies very ordinary and tedious. Here are some fun alternatives:
1. Thank you for your e-mail. Your credit card has been charged $5.99 for the first ten words and $1.99 for each additional word in your message.
2. Thank you for your message, which has been added to a queuing system. You are currently in 352nd place and can expect to receive a reply in approximately 19 weeks.
